Four students are arguing over why the kids keep falling in the video. lan says "When the child kicks the ball, the ball is more massive than the child's foot, so the force of the ball on the foot is greater than the force of the child's foot on the ball. According to Newton's 2nd Law, this unbalanced force propels the child's foot backwards and the child falls." Tammy says, "According to Newton's 3rd law, the force on the ball and the force on the foot are equal and opposite, so the reason the child falls is that the child is lighter than the ball." Jordan says "According to Newton's 1st law, since the child is in motion they will want to stay in motion. When the force of the ball acts on the foot, the foot stops unexpectedly, and the child falls forward because inertia keeps the rest of the child's body in motion." David says "According to Newton's 1st law, the ball is at rest and wants to stay at rest. When the child kicks the ball, Newton's 2nd law says the force of gravity keeps it still, and Newton's 3rd law means the reaction force of gravity flips the child's foot up in the air and flips them." hich student gives the most accurate explanation of the physics behind the falls?
