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." hat change in reasoning would make Jordan's explanation more appropriate/correct? O The foot doesn't stop completely, it feels a force opposite its motion that slows it relative to the rest of the body. O The force of the ball does not act on the foot, the force of the foot acts on the ball. O Newton's 1st law states objects in motion want to come to rest. Inertia doesn't keep the child's body in motion, the force of the ball propels the foot backward.

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 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."
force of
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."
What change in reasoning would make Jordan's explanation more appropriate/correct?
O The foot doesn't stop completely, it feels a force opposite its motion that slows it relative to the rest of the body.
O The force of the ball does not act on the foot, the force of the foot acts on the ball.
O Newton's 1st law states objects in motion want to come to rest.
O Inertia doesn't keep the child's body in motion, the force of the ball propels the foot backward.
