real simple question (1 Viewer)

i no this is a real simple question and i no the answer but i wanted 2 no why..
it is said that 2 objects wateva mas they are fall at same time (no air resistance). but wen u lift a heavy object its GPE is greater say at like 2m height than the GPE of a light object at that height (we assuming we r on earth). and as the 2 objects fall the mass with the greater GPE should hav a greater kinetic energy as it falls.. dont that basically mean that it is moving faster???? :S

somethings in physics are not meant to be understood at the school level. somethings u just gotta take as fact and law, like if u learn relativity in year12.

greater mass = greater momentum?..

They will have the same speed.
KE=1/2mv²
As the mass is greater, the KE is greater.

Work is directly related to a change in energy. The change in energy is not directly related to velocity, there are other factors like mass, types of energy that are involved.

yeah sometimes you just have to accept it no matter how wrong it seems
