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 car 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.

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.
