Describe how a newton's cradle illustrates the conservation of energy. a) dropping the ball transfers the gravitational energy to the others causing the ball on the opposite side to swing up. b) swinging the ball into the others, transforms the endothermic energy causing the ball on the opposite side to swing up. c) impacting the ball into the others, fixes the exothermic energy to the balls causing the ball on the opposite side to swing up. d) as the ball drops and impacts the others, the energy is transferred through the balls causing the ball on the opposite side to swing up.
