Use the diagram to answer the question.

Brennan is traveling in a car at a constant speed. He quickly applies his brakes and stops to avoid an accident. Brennan’s body continues to move forward and is stopped by the seat belt. Why?

• an object in motion remains in motion unless acted on by an unbalanced force

• for every action there is an opposite equal reaction

• when mass increases a greater force is needed to accelerate the object

• the law of gravity
