Homework Statement


You throw a ball. When the ball is many meters away from you, is the force of your hand still acting on the ball?

2. The attempt at a solution
My thoughts are:
No because it's many meters away.
Yes because it's still moving from the throw.

I have no idea which is right :(

The answer is no. The force exerted by your hand was necessary to cause a change in motion, but not necessary for motion itself. This point was the fundamental difference between Newtonian and Aristotelian mechanics.
