A large heavy rock and a small light rock are held in a net 2meters above the ground. When they are dropped, which will have greater kinetic energy. Why?

The heavy rock will have the greater kinetic energy because since it is larger, it has more mass. As a result, it will fall to the ground faster turning the kinetic energy to potential energy.

Hope this helps :)
