What is Newton's First Law of Motion also known as?

• Law of Inertia

• Law of Acceleration

• Law of Universal Gravitation

• Law of Action and Reaction

According to Newton's First Law, what will an object in motion do if no unbalanced force acts on it?

• It will change direction

• It will stop

• It will continue moving at the same speed and direction

• It will accelerate

What does Newton's First Law imply about objects and external forces?

• Objects change their state randomly

• Objects continue their state unless acted upon by an external unbalanced force

• Objects need a force to stay at rest

• Objects need a force to stay in motion
