A light object and heavy object are placed on two identical vehicles. The lighter object falls but the heavy one doesn't. But if mass is directly proportional to inertia the light object shouldn't have resisted much to its change in state of motion while the vice versa should have happened to the heavier object. Then why does it differ in the real world? |
