A student is investigating Newton's laws using a soccer ball, a volleyball, and a basketball. The student places each ball on the ground. The student then kicks each resting ball into a net. The ball bounces out of the net, back toward the student, and rolls on the ground before coming to a complete stop. The student kicks each ball with a force of 100 Newtons and 200 Newtons.

The results are shown.

Each time the student kicks the ball into the net, the ball bounces and then rolls back toward the student before coming to a stop. Which statement correctly uses Newton's Laws of Motion to describe the forces and motion of the soccer ball?

• The soccer ball changes its motion after hitting the soccer net.

• The soccer ball does not change its motion after hitting the soccer net.

• The soccer net exerts a force on the ball in the same direction the ball is traveling.

• The soccer ball exerts more force on the soccer net than the net exerts on the ball.

Drag and drop the choices to match each example with the corresponding law of motion.

• Newton's Second Law

• The ball is resting on the ground before it is kicked

• Newton's First Law

• The ball accelerates at different rates, based on the force of the kick

• Newton's Third Law

• The ball pushes back on the student when it is kicked

Maria dropped four different objects in a vacuum. The graph shows the data she collected. Which statement best describes the data Maria found?
