No forces act on the ball while it is in free fall b. The gravity due to the earth; the reaction force is the gravity due to the ball pulling on the earth. c. The force due to gravity of the earth puling down on the hand; the reaction force is the force due to gravity of the hand puling up on the earth d. he force of the hand pushing up on the ball; the reaction force is ball pushing down on the hand
