The ping pong ball has less mass and therefore experiences less inertia, resulting in a lower force required to move it compared to the bowling ball.
The force required to move a ping pong ball is less than the force required to move a bowling ball because the ping pong ball has less mass, resulting in less resistance to motion.
The force required to move a ping pong ball is less than the force required to move a bowling ball because the ping pong ball has less mass and therefore less inertia to overcome.
