Forces in Two Directions


Can 2N + 2N = 2N? Post the Launch Lab for chapter 5 here. Answer the analysis question in your conclusion in addition to the standard lab conclusion questions.

Objectives: Evaluate the sum of two or more vectors in the same or opposite directions.

Hypothesis? Under what conditions can two different forces equal one other force?
- When one force is greater then the other. Because if they are equaled out then they will not have the same force.

Procedures:
1. Measure and record the weight of 200grams.
2. Use a 35 cm string attach it to the bottom of each scale.
3. Tie one end of the 15 cm string to the 35 cm string. and tie the other to the other end.

Data:
1. The first time we started to pull it was even at a weight of 1.2 newtons which is equivalent to 110grams.

2. on the second pull is stayed the same. nothing changed.

3. On the next pull the left side was less then the right side. Left= 1.5 newtons= 150 grams. Right side= 2 newtons= 200 grams.

4. On the last session the left side was greater than right side. left side= 3 newtons= 300 grams. Right side= 2.3 newtons= 230 grams.

Conclusions- Not the sum of the forces does not weight the same as the weight because no matter how far you pull the string the weight will always be more.

Objective: Evaluat3e the sum of two or more vectors inthe same or opposite direction.
Hypothesis: when can two different forces equal one force?
Procedures:
1.Measure and record the weight of the 200gmass.
2. Use a 35cm string attach it to the bottom of each scale.
3.Tie one end of the 15cm string to the 35cm string,and tie it to the other end.
data:1. The first time it was 100grams
2.It was 100grams nothing changed.
3.It stayed the same nothing changed.

Conclusion: The forces equals the same as the weight every time we pulled the string it stayed the same.

Objectives: Evaluate the sum of two or more vectors in the same or opposite directions.

Hypothesis: Under what conditions can two different forces equal one other force?
- Two different forces can equal one force when the two forces are put together. I believe that the two scales will equal more than the 200 gram mass.

Procedure:
1)Measure and record the weight of the 200g mass.
2)Use a 35cm string and attach it to the bottom of each scale.
3)Tie one end of the 15cm string to the 35cm string, and tie it to the other end.

Objectives: Evaluate the sum of two or more vectors in the same or opposite directions.

Hypothesis: Under what conditions can two different forces equal one other force?
- I believe that under the conditions of two force colliding with each other it can equal to one force.

Procedure:
1)Measure and record the weight of the 200g mass.
2)Use a 35cm string and attach it to the bottom of each scale.
3)Tie one end of the 15cm string to the 35cm string, and tie it to the other end.

Data:
Trial 1: when pulling the strings scale read 1.5N
Trial 2: when pulled more scale read 2N
Trial 3: when pulled again scale still read 2N

Conclusion: In my conclusion it was create because in order to complete this experiment you had to connect both the scale to 200g mass which made it equal to one force.
