It's according to the inertia (Newton's first law) the ability of heavy body to keep its state is more than the ability of light bodies(you can call it resistance one has more than the other).
when you kick a ping ball it could be damage while Billiard ball couldn't and the speed would be much higher.
By using math F =m a (take f is constant and go on).

since  a is inversely prop to mass   as mass increases   accl  decreases  and vice versa

because nature likes it that way
