Jose wants to know the effects of mass, force, and surface type on the motion of a small box. He has one spring, one box, and an assortment of weights to put in the box. He compresses the spring between the box and a wall, measures how far he has compressed it, then releases the box. He then measures how far the box travels before stopping. The table below presents the data he collected.
