Suppose you drop two books of different masses from the same height, which will hit the ground first?

Sagot :

we can infer in the inertia the lesser mass, in acceleartion the greater force but it totally same they will fall down in the same time 
because all things surround in the earth is go in the earts surface
we can say the GRAVITY.

>Hope it helps

don't copy my answer,it is based on my mind !!

Relate it to Law of interaction. The one with greater mass will hit the ground first. Because, gravity has only one measurement and that is 9.8. The one with greater mass has the tendency to fall down faster that the other one and hit the ground first.
