Answer:
Weight makes no difference. But different sizes and starting points do,
If the balls are the same size and weight, then the one that starts higher will hit the ground with greater speed because it has further to accelerate.
However, if they are the same weight but different sizes, then the smaller one will have a lower friction from the air and will fall faster and hit harder, depending on the relation between their starting height and friction from the air.
For example, an inflatable beach ball and a little ball bearing might have the same weight, but the ball bearing would fall a lot faster. I bet if you dropped the ball bearing from 10 metres it would hit faster than the beach ball dropped from a couple metres up.
