i would have believed anything thrown at me to be true. Santa Clause is Indian, Obama cant make pancakes or Christmas is in July. Never would have I ever believed that Glass balls bounce higher than Rubber Balls. How??!! that was the first question i asked when i also got wind of this fascinating piece of information.
its complicated yes, but let me break it down to you as simple as i can. when rubber balls fall to a surface, the energy they possess causes it to deform. the deformation happens because of the elastic nature of the material. the force and energy gained while the ball is dropping is mostly lost when the ball deforms as the pressure acts on it. as the ball regains shape and elastic force acts much of the energy is lost and hence the ball cant bounce that high as compared to a glass ball that little to no elasticity at all. when the glass ball touches the surface after it falls the material is more compact and less elastic hence the energy gained by the ball is retained and hence the glass ball has sufficient energy within to bounce back, in this case, higher than the rubber ball.
a vague argument i could also level comes from Newton 3rd Law of Motion that states for every action,there is an equal and opposite reaction. coming back to our glass ball. the force that the glass ball gains as it falls kinetic energy helps the glass ball bounce back higher as the reaction in this case comes into effect after the glass ball touches the surface.
this is my vague view on the glass ball. i stand to be corrected or seconded. feel free to share your comments below.
