Describe how Newton's Third Law of Motion is demonstrated when a swimmer pushes off the wall of a pool.

• The swimmer moves forward because the wall pushes back with equal force.

• The swimmer moves forward because the water pushes them.

• The swimmer moves forward because of gravity.

• The swimmer moves forward because of friction.

Explain how Newton's laws of motion apply to a roller coaster ride.

• Newton's First Law keeps the ride moving, Newton's Second Law determines the speed, and Newton's Third Law explains the forces between the ride and the track.

• Only Newton's First Law applies as the ride is in motion.

• Only Newton's Second Law applies as it involves acceleration.

• Only Newton's Third Law applies as it involves action and reaction.
