Describe how seatbelts in a car demonstrate Newton's First Law of Motion.

• They provide a force to stop passengers from moving forward when the car stops suddenly.

• They increase the speed of the car.

• They decrease the mass of the passengers.

• They change the direction of the car.

Which of the following best describes Newton's Third Law of Motion?

• An object at rest stays at rest.

• Force equals mass times acceleration.

• For every action, there is an equal and opposite reaction.

• The acceleration of an object is inversely proportional to its mass.

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

• The wall pushes back on the swimmer with an equal and opposite force, propelling the swimmer forward.

• The swimmer's mass decreases, allowing them to move faster.

• The water increases its resistance against the swimmer.

• The swimmer's speed remains constant.
