A child tosses a ball straight up. She says the ball is moving away from her hand because the ball feels an upward "force of the throw" as well as the gravitational force.
(a) Can the "force of the throw" exceed the gravitational force?
(b) Can the "force of the throw" be equal in magnitude to the gravitational force?
(c) What strength can accurately be attributed to the force of the throw?
(d) Why does the ball move away from the child's hand?
