Which of the following items are affected the most by the force of gravity?

A. A tennis ball

B. A golf ball

C. A baseball

D. A bowling ball

The bowlingball because it is the heavest which will cause it to fall faster thus showing it is the most affected by gravity.

I would say all of them are affected by gravity - everything on the planet of earth is affected by gravity it pushes everything back down, however, if I had to make a guess I would say baseball because there is more gravity applied to the force of the ball than there is used in any other game listed.
