That means it gained kinetic energy, implying object 2 transferred energy to object 1, in contrast to our initial interpretation. During the exercises ERS™ teams work as close to real conditions as possible and upon completion provide summary report. 30). 2 In an inelastic collision, the bodies collide and (possibly) come apart again, but now some kinetic energy is lost (converted to some other form of energy). In this chapter on collisions, we shall have occasion to distinguish between elastic and inelastic collisions. This “total body activation” is readily observable if an athlete performs a collision prep exercise without a shirt on.
