For throwing a baseball, the force you exert on the ball makes the ball change direction and speed. It's harder to throw a bowling ball, isn't it? That's because Newton’s Third Law of Motion tells us to expect a bowling ball to exert a larger force on your hand than a beachball. If you feel a force, it's because one is being exerted on you by the ball. Does that help?

acceleration equals force divided by mass
