Write a hypothesis for Part II of the lab, which is about the relationship described by F = ma. In the lab, you will use a toy c

ar and apply forces to it. Use the format of "if . . . then . . . because . . .” and be sure to answer the lesson question "How can Newton's laws be experimentally verified?” specific to Newton’s second law.

For e2020 this is the simple answer "If force is applied to a car, then its acceleration will change proportionally, as predicted by Newton’s second law, F = ma."

{Just did this} But I used "If the toy car has force applied to it then the force would leave no choice but to move the toy car in whichever direction it is applied because the force would move the toy car according to Newton's laws." and got it right.

If you increase the mass m of the car, the force F will increase, while acceleration a is kept constant. Because F and m are directly proportional.
If you increase the acceleration a of the car, the force F will increase, while mass m is kept constant. Because F and a are directly proportional.

How can Newton's laws be verified experimentally; is by setting this experiment, and changing one variable while keeping the other constant, then observe the change in F.

Hope this helps.
