Assuming that it is pure energy transfer, meaning no energy lost to friction, sound energy, heat energy or others. Will the lighter ball rebounce or not? After you have answered, pls check:
==>If you say that it will rebounce, then Newton said that when object A acts a force on object B, object B acts an equal and opposite force on object A. So shouldn't this force and the force the lighter object originally had balance out one another (just like when the two balls are of the same mass).
==>If you say it will not rebounce, then why is it that when you drop a ball on the Earth, it will bounce back to its original height assuming no energy lost when bouncing? Shouldn't it just bounce the amount the Earth moved (which is insignificant to the human eye)?
