CONCEPTS AT A GLANCEIn projectile motion, the horizontal or x component of the acceleration is zero, and the vertical or y component of the acceleration is the acceleration due to gravity. In this time-lapse photograph, the cat exhibits projectile motion while in the air, assuming that the effects of air resistance can be ignored. ( Stephen Dalton/Photo Researchers).
