What is Newton's First Law known as? The Law of

An object in motion will stay in what kind of motion as long as the net forces acting on it are zero?

• slowing motion in a straight line
• accelerating motion in a straight line
• constant motion in a straight line
• constant motion in an unpredictable direction

What is Newton's First Law

• F=ma
• Every action has an equal and opposite reaction
• An object at rest stays at rest, an object in motion stays in motion. 
• Friction 

A resistance to a change in motion is 

• Acceleration
• Inertia
• Gravity
• Velocity

The inertia of an object depends on its

• mass
• speed
• velocity
• direction

An object at rest will stay at rest unless an unbalanced force acts on it.

• True

• False

An object that is changing position (location) is

• at rest

• in motion

Friction can make a moving object slow down or stop.

• True
• False
