Experiment 4

Objectives: To see if it takes more force to change the speed or direction of a moving object. Then the initial speed.

Hypothesis: The force will be greater than because if you want to change the speed then you have to put in more work.

Materials: 200 g mass, string, spring scale, cart

Procedures: 1. Set up the equipment
2. We pulled on the string 4-5 times to see what changes we could find.
3. Recorded our results.
4. Then we pulled the string in an arc direction to see the changes we could find.
5. Recorded our results.

Data 1:
a. 100g
b. 150g
c. 100g
d. 120g
e. 150g

Data 2:
a. 200g
b. 150g
c. 200g
d. 150g
e. 100g

Analyze
It takes more force to maintain it's initial speed. Because you would have to push the cart harder to get the speed to accelerate. I t takes mote force to change the direction of the cart. When you change the direction you pull harder which causes the spring scale grams to go up.
My conclusions was correct.
