Objective: To test Newton’s first law with respect to objects in motion. Objects in motion will stay in motion unless acted upon by an external force.
Hypothesis: I think the 100-gram mass will not fly off the hall’s cart. I think it will just move or not move at all.
Materials:
Hall’s Cart
100-gram mass
Cardboard
Wooden ramp
Procedure:
1. Place the wooden ramp on the floor.
2. Tape a piece of cardboard over the hole in Hall’s Cart.
3. Put the 100-gram mass on top of cardboard.
4. Gently push car so it hits the edge of the ramp. Repeat 4-5 times.
Data:
Trial Mass
1 Mass moved
2 Mass moved
3 Mass flew off
4 Mass moved
5 Mass moved
Conclusion:
My hypothesis was both correct and in correct. It was correct because the 100-grams did move. It is incorrect because it didn’t stay still and it did fly off the cart. If I could change the lab, I would of use the material differently. I would have taken the cardboard off to see if the mass would move the same ways. To better the results I would move the cart at different speeds to see how the mass would move. I learned that when an external force interferes with an object it makes that object move in different directions. The concepts can be use in everyday life because it shows what will happen if something is push with being protected which can help with babies I strollers.
Objective:Was to see if objects in motion really continue in motion unless acted upon by an external force.
Hypothesis: The mass will not slide or fly off the cart. I think it will just sit there.
Materials Used:
-cardboard
-wooden ramp
-cart
-100g of mass
Procedure:
First place the wooden ramp on the floor. Then tape a piece of cardboard over the hole of the cart. Then put 100g mass on top of the cardboard. Push the cart so that it collides with the edge of the wooden ramp. Do this at least 4 to 5 times.
Data:
1.The cart didn't really hit the ramp in the mass didn't move.
2.The cart hit the wooden ramp gently in the mass fall off.
3.the Cart hit the ramp and the mass fall off.
4.The mass move off the cart.
Conclusion:
In this experiment the cart did the same thing. The mass just fall off the cart differently. But all times it look the same. This proved that by placing mass on a cart while moving it will not stay still. It might if going really slow but most likely it wont.
Experiment 3:
Objective: To prove that objects in motion don't continue to be in motion unless acted upon external force.
Hypothesis: I think that when you push the cart the 100 g mass will fall off of the cart.
Materials Used:
1. ramp
2. cart
3. tape
4. cardboard
5. 100g mass
Procedure:
1. Place the wooden ramp on the floor
2. Tape a piece of cardboard over the hole in the Hall's cart
3. Put the 100 g mass on top of the cardboard as illustrated
4. Gently push the cart so that it collides with the edge of the ramp. You must push the cart gently enough so that the mass does not move until the cart hits ramp.
Data:
Trial 1- 100g mass falls
Trial 2- 100g mass rolls on the board
Trial 3- 100g mass falls on the floor
Trial 4- 100g mass rolls on the floor
Conclusion:
1. It kept falling and/or rolling on to the ramp or the floor.
2. Yes, my hypothesis was correct
3. Yes, it follows Newton's First Law
4. Nothing really went wrong, except when we would collide the cart with the ramp it would fall and roll on the floor.
5. I couldn't see using this in a real word application
6. I learned that when driving always wear a seat belt.

Objective: To test Newton’s first law with respect to objects in motion. Objects in motion will stay in motion unless acted upon by an external force.
Hypothesis: I think the 100-gram mass will somewhat fall off the cart, but it will move.
Materials:
Hall’s Cart
100-gram mass
Cardboard
Wooden ramp
Procedure:
1. Place the wooden ramp on the floor.
2. Tape a piece of cardboard over the hole in Hall’s Cart.
3. Put the 100-gram mass on top of cardboard.
4. Gently push car so it hits the edge of the ramp. Repeat 4-5 times.
Data:
Trial Mass
1 Mass moved
2 Mass moved
3 Mass flew off
4 Mass moved
5 Mass moved
My hypothesis was correct, that's because it did move. As well it proved to me that it was going to fall off.
Objective: To see if objects in motion really continue in motion unless acted upon by a external force.
Hypothesis: I think the 100gram will fall of the top.
Materials: 100g mass, ramp, cart, duck tape, card board
Procedures: 1. We put the card board on the top cart.
2. Taped two pieces of tape to the card board so it would stay together.
3. Place to 100g mass gently on the top of the card board.
4. Push the cart gently so that it hit the ramp. But always so that the mass don't come off before it hits.
5. Recorded our data
Data:
a. The mass went forward and landed on the ramp.
b. The mass went forward.
c. The mass fell backwards onto the floor.
d. The mass fell on the back wheel e. The mass fell flat to the ground.
Conclusion: The weight is knocked off of the cart. A force is acted upon. In this case the force is the ramp. Yes my hypothesis was correct. The weight did fall of the ramp.

Objective: To tryout Newton’s first law motion. Objects in motion will stay in motion unless acted upon by an external force.
Hypothesis: I believed that Hall's Cart would stay on the board and not fall off the table.
Materials:
Halls Cart
100-gram mass
Cardboard
Wooden ramp
Procedure:
1. Place the wooden ramp on the floor.
2. Tape a piece of cardboard over the hole in Hall’s Cart.
3. Put the 100-gram mass on top of cardboard.
4. Gently push car so it hits the edge of the ramp. Repeat 4-5 times.
Data:

Objects in motion remains in motion
Objective
To test Newton’s first law with respect with object in motion. Object in motion will stay in motion unless acted upon by an external force.
Hypothesis
I think that the 100 gram mass will move and fall off.
Materials
Hall’s Cart
100-gram mass
Cardboard
Wooden ramp
Procedure
1. Place the wooden ramp on the floor.
2. Tape a piece of cardboard over the hole in Hall’s Cart.
3. Put the 100-gram mass on top of cardboard.
4. Gently push car so it hits the edge of the ramp. Repeat 4-5 times.
1st
Mass fell off
2nd
Mass fell off
3rd
Mass fell off
4th
Mass stayed on
5th
Mass fell off
Conclusion:
In this experiment it just kept on doing the same thing in every trial.
The mass fell off different times but the cart kept moving.
Experiment three
Object: Does motion remain in motion.
Hypothesis: I believe that when the halls cart collides into the wood ramp I thing that the 1000 g mass will fall off the halls cart.
Procedure: First we place the wooden ramp on the floor.
Then we place a piece of cardboard over the hole in the hall’s cart.
Then we put the 100gmass on top of the cardboard.
When finally gently push the cart so that it collides with the edge of the ramp.
Data:
1. The 100g mass felt on the floor.
2. The 100g mass when into the wooden ramp and land on top of the wood ramp.
3. The 100g mass felt off the back of the hall’s cart and land on the floor.
4. When push the 100g mass in then land felt off once more and land on the side of the hall’s cart.
Conclusion: To my understanding my Hypothesis was right was correct. The reason why it was right is because I could just look at the object that was given to use a see that the 100 g mass was going to fall off top of the hall’s cart.
If I could go back in time I will first change how we sat up the hold experiment my put some thing on the 100 g mass so that it would not fall off the hall’s cart.
In the experiment noting really when wrong .In this experiment I learn that any thing in force of moving will fall off my fore.
I also will have to say that I will use this experiment in everyday life by convert test this with airplanes and cars for a better safe.
Objects In Motion Remain In Motion
Objective: The objective of this lab is to see if objects in motion really continue in motion unless acted upon by an external force?
Hypothesis: I think that the 100g mass will fall on the floor once it collides into the ramp.
Materials Used: 1OOg mass, wooden ramp, Cart.
Procedure: 1.Place the wooden ramp on the floor.
2. Tape a piece of cardboard over the hole in the Hall’s cart.
3. Put the 100 g mass on top of the cardboard as illustrated.
4. Gently push the cart so that it collides with the edge of the ramp. You must push the cart gently enough so that the mass does not move until the cart hits the ramp. Repeat 4-5 times.
5. Analyze your results. What happens to the 100 g mass when the cart is acted upon by the external force for the ramp? Was your hypothesis correct? Does the mass follow Newton’s First Law?
Data:
Trial 1 Fell
Trial 2 stayed
Trial 3 Fell
Trial 4 stayed
Graphs/Pictures:
Conclusion: 1. When the 100 g mass is acted upon the external force of the ramp the 100g mass fall’s off the cart.
2. Yes our hypothesis was correct.
3. Yes the mass follow Newton’s first law because when we pushed the cart the 100g mass fell off the cart which was a reaction.
Experiment 3:
Objective: that objects in motion don't continue to be in motion unless acted upon external force.
Hypothesis: I believe that when the the cart is pushed the 100g will fall off of the cart.
Materials:
1. ramp
2. cart
3. tape
4. cardboard
5. 100g mass
Procedure:
1. Place the wooden ramp on the floor
2. Tape a piece of cardboard over the hole in the Hall's cart
3. Put the 100 g mass on top of the cardboard as illustrated
4. Gently push the cart so that it collides with the edge of the ramp. You must push the cart gently enough so that the mass does not move until the cart hits ramp.
Experiment trials:
Trial 1- 100g mass falls
Trial 2- 100g mass rolls on the board
Trial 3- 100g mass falls on the floor
Trial 4- 100g mass rolls on the floor
Conclusion:
As a conclusion to our experiment my conclusion was right from the beginning. the 100g did fall off the cart each time we did a trial.
Experiment: Objects in motion remain in motion.
Objective: To prove that objects in motion continue to be in motion unless acted upon an external force.
Hypothesis: Once the cart collides with the edge of the ramp the 100g mass is going to roll off the cardboard.
Procedure: 1. Place the wooden ramp on the floor.
2. Tape a piece of cardboard over the hole in the Hall’s cart.
3. Put the 100g mass on top of the cardboard.
4. Gently push the cart so that it collides with the edge of the ramp. You must push the cart gently enough so that the mass does not move until the cart hits
the ramp. Repeat 4-5 times.
5. Analyze results. Draw conclusion.
Data:
Trial 1- The 100g mass falls on the floor.
Trial 2- The 100g mass rolls onto the board,
Trial 3- The 100g mass falls on the floor.
Trial 4- The 100g mass rolls on to the floor.
Trial 5- The 100g mass rolls on the board.
Conclusion: After performing this experiment and seeing first hand that the 100g mass fell during every trial, I am convinced that when influenced by an external force an object in motion remains in motion. The 100g mass was in motion while it was on top of the cart and remained in motion when it fell of the floor. Taking a look at Newton’s first law of motion and after witnessing this experiment, his law is absolutely true. My hypothesis was proven to be correct once the cart came in contact with the board the 100g mass did roll of the cardboard every time. Though this lab ran smoothly with no errors, I believe that it would have been more accurate if there were more trials done and the cart we used was bigger. I learned that an object in motion really remains in motion without any discrepancies. In real life, when someone is running at a fast pace it takes time for them to stop unless they impact a force. The same lesson that was learned by doing this experiment can be applied to forms of movement made everyday.

Procedure:
1. Place the wooden ramp on the floor.
2. Tape a piece of cardboard over the hole in Hall’s Cart.
3. Put the 100-gram mass on top of cardboard.
4. Gently push car so it hits the edge of the ramp. Repeat 4-5 times.

Experiment #3
Physicist Symone Gladden
Physicist DArren Gibson
Physicist Yanique Tomlinson
Objective: Do objects in motion really continue in motion unless acted upon by an external force?
Hypothesis: Yes, objects do contunue in motion unless acted upon by an external force. I believe the 100 gram mass will fall when it collides with the ramp.
Materials: Hall's cart. cardboard, wooden ramp, 100 gram mass
Procedure
1)Place the wooden ramp on the floor.
2)Tape a piece of cardboard ove the hole in the Hall's cart.
3)Put the 100 gram mass on top of the cardboard.
4)Gently push the cart so that it collides with the edge of the ramp. You must push the cart gently enough so that the mass does not move until the cart hits the ramp. Repeat 4-5 times.
Data
Trial 1-----the mass falls of the cart
Trial 2-----the mass falls of the cart
Trial 3-----the mass falls of the cart
Trial 4-----the mass slides onto the ramp
Conclusion:
The objective of this experiment was to see if objects stay in motion unless acted upon by an external force.My hypothesis was that an object would not continue to move because it will eventually slow down at rest because of an external force. For example, if you push a cart with you hand it will not continue to move at the same speed it started off with. I also thought that the 100 gram mass would fall when the cart collided with the ramp. My hypothesis was correct.
On the first trial the 100 gram mass fell off the cart to the floor. The same thing occured for trials two and three. However,on the last trial the mass slid on the ramp. So when the cart was acted upon by an external force with the gram on top of it the mass moved swiftly. The mass follows Newton's law because it states that objects will only move if it's acted upon by an external force.
If we could of done the experiment again I would of done six trials instead of four. I also would have chosen a different cart to use. The thing that went wrong was trying to push the cart at the same spot at the same speed each time. A real life application is an automobile. When a car collides into a wall creating a car crash, the passenger will have a reaction and the car will have a reaction.
Objective: To see if an object in motion stay in motion without be forced upon an external force.
Hypothesis: The mass in the hall's cart will not fall out. It will stay in becasue there is no force to make it fall out.
Materials: -cardboard
-wooden ramp
-cart
-100g of mass
Procedure:
First place the wooden ramp on the floor.
Then tape a piece of cardboard over the hole of the cart.
Then put 100g mass on top of the cardboard.
Push the cart so that it collides with the edge of the wooden ramp. Do this at least 4 to 5 times.
Data:
1.Pulling the cart by the string.
2.Gently forcing to move toward the edge of the ramp.
3.The cart hit the edge of the ramp and it fell off.
Conclusion: My hypothesis is incorrect. I thought that the mass in the cart will weigh the cart down. Around all I learned that althrough something look like it would be in your favor it does not always come out like that.
Real World: I think that we can apply this in our everyday lifes by looking and taking guesses and then seeing our results of things. For example if we are moving something with an object on top of it then we know it has a good change of fall it we do not carry it out right.

Objects in Motion Remain In Motion
Experiment #3
Objective: The objective of this experiment is to use Newton’s first law and find out whether objects in motion really continue in motion.
Hypotheses: I predict that the 100g mass will fall to the floor once it hits the ramp.
Materials: halls cart, 200g mass, ramp, string, and the spring scale.
Producers: 1. Place the wooden ramp on the floor.
2. Tape a piece of cardboard over the hole in the Hall’s cart.
3. Put the 100g mass on top of the cardboard as illustrated.
What do you think will happen to the 100g mass when you push the cart so that it collides with the edge of the ramp?
4. Gently push the cart so that it collides with the edge of the ramp. You must push the cart gently enough so that the mass does not move until the cart hits the ramp. Repeat 4-5 times.
5. Analyze your results. What happens to the 100 g mass when the cart is acted upon by the external force of the ramp? Was your hypothesis correct? Does the mass follow Newton’s first law?
Data:
Trails Halls Cart Recording
1st Fell
2nd Stayed
3rd Fell
4th Fell
Conclusion: My hypothesis was correct I predicted that the 100g mass would fall once it hit the ramp and indeed it did. I learned how objects in motion really continue in motion. My data is simply talking about what happen each time the cart collided into the ramp. Nothing really went wrong after we set the materials up that was given to us, it was easy because the instructions were detailed. I think this could be used in the real world because for instance a parked car being hit by a car in motion is an example of objects in motion remains in motion.
