Newton's second law is F = ma. In this task, you will plan two controlled experiments to see how changes in force and changes in
mass affect the motion of the box in the hanging weight simulation from task 1. Because you don’t have access to special measuring devices, you’ll just use observation to compare the acceleration of the box as it moves across the table. You should change only the force or the mass, but not both, because these are controlled experiments. estimated time to complete: 20 minutes
Part A
Plan a controlled experiment that uses the simulation to investigate how changing the mass of an object changes its acceleration. The net force on the object must stay the same. Record your plan here.
