Experiment 2

Experiment 2

My Hypothesis: I think it will be more force will be applied by start rather then more force will be applied by the constant speed.

Answers to number 8
1. I really believe it took more force to start then to be a constant speed.
2. My hypothesis was correct. It did take more force to start then to keep it going.
3.Yes, Newton’s first law for a body at rest.

• My Hypothesis: I believe that the ramp will make the cart roll off but it will stay on the table. It might just even roll back on the table.

Trials My Observation
1 I observed that the cart stayed on the table. The cart rolled a little forward.
2 “ ‘ ‘ ‘ ‘ ‘ “
3 I observed the cart rolled towards the back. It stayed on the table.
4 It rolled towards the front, and it also stayed on the table
5 “ “ “ “


• Was my Hypothesis correct: Yes, it was correct in some form of way. It did not roll backwards but it did stay on the table.

• Yes it follows Newton’s first law for a body at rest.
