27. When you throw a ball upward, what force pushes it upward?
To throw the ball upward, you temporarily push upward on it with a force greater than its weight. The result is that the ball has a net force (the sum of all forces on the ball) that is upward. The ball responds to this upward net force by accelerating upward. You continue to push upward on the ball for a while and then it leaves your hand. By that time, it's traveling upward with a considerable velocity. But once it leaves your hand, it is in free fall. Nothing but gravity is pushing on it—it's carried upward by its own inertia! In fact, it's accelerating downward at 9.8 m/s^2. It rises for a while, but less and less quickly. Eventually it comes to a stop and then it begins to descend.
