4.1 The Concepts of Force and Mass
... 6.5.1. Two balls of equal size are dropped from the same height from the roof of a building. One ball has twice the mass of the other. When the balls reach the ground, how do the kinetic energies of the two balls compare? a) The lighter one has one fourth as much kinetic energy as the other does. b ...

... demonstrates that an object’s acceleration is proportional to the vector sum of the forces acting on it . In this experiment, shown in Figure (5), we attach one end of a spring to a nail, hang a ball on the other end, pull the ball back off to one side, and let go. The ball loops around as seen in t ...
