Newton's first law is often referred to as:

• the law of order
• the law of friction
• the law of inertia
• the law of gravity

If a body in motion resists a change in velocity, why does a marble in motion on the earth's surface stop after a period of time? 

• because of the sticky gum theory
• because of friction
• because of the greenhouse effect
• because it wants to stop

What is Newton's First Law?

• Objects may be moving even when they do not appear to be.
• An object in motion or at rest will tend to stay in motion or at rest until it is acted upon by an outside force.
• When an object is acted on by one or more outside forces, the total force is equal to the mass of the object times the resulting acceleration.
• For every action, there is an equal and opposite reaction.

What is Newton's Third Law?

• Objects may be moving even when they do not appear to be.
• An object in motion or at rest will tend to stay in motion or at rest until it is acted upon by an outside force.
• When an object is acted on by one or more outside forces, the total force is equal to the mass of the object times the resulting acceleration.
• For every action, there is an equal and opposite reaction.
