The three factors influencing the coefficient of restitution are the materials of the interacting bodies, the velocity of the collision and the temperature of the materials involved. The temperature of the materials involved does not affect this experiment. If all three balls were to be dropped at the same height onto the concrete ground, the golf ball would be much more bouncy compared to the practice ball and air ball. The practice ball would then be the second most bouncy, followed by the air ball. This is due to the materials of the interacting bodies, as the golf ball has materials that enable it to have a coefficient of restitution closer to one. By the golf ball having a coefficient of close to one, the ball is able to produce a greater horizontal displacement compared to the other two balls. Newtons 2nd Law (F=m.a) relates to the behaviour of objects when all forces are unbalanced, resulting in the development of acceleration. To increase acceleration, force must be applied, assuming the mass is held constant. In this experiment the mass of the balls vary from the air ball being the lightest to the golf ball being the heaviest. Due to the force applied on each ball by the golf club remained the same, the initial acceleration on the air ball was greater than the golf ball. This initial acceleration being greater only lasted less
