What is Newton's First Law of Motion?

• F=m x a
• Every action has an equal and opposite reaction
• An object at rest stays at rest, an object in motion stays in motion unless acted on by another force. 
• Friction 

What is inertia?

• the force that opposes motion

• the force of attraction between 2 objects

• an object's tendency to stay in its state of motion

• a change in an object's speed and/or direction

According to Newton’s first law of motion, a moving object that is not acted on by an unbalanced force will

• remain in motion.
• eventually come to a stop.
• change its momentum.
• accelerate.

What is the net force on an object?

• the sum of all the forces on an object

• the negative forces on an object

• the positive forces on an object

• the balanced forces on an object

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

• Friction
• Mass
• Inertia
• Gravity

The law of inertia (Newton’s First Law) applies

• to both moving and nonmoving objects
• only to moving objects
• only to objects that are not moving

• it has more mass

• it has more volume

• it is not as aerodynamic

• It has more space
