Newton's Laws of Motion

Multiple Choice

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 

Multiple Choice

• zero net force
• balanced forces
• unbalanced forces

Multiple Choice

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.

Multiple Choice

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

Multiple Choice

What is inertia?

• the force that opposes motion
• the force of attraction between 2 objects
• an object's tendency to stay in motion or to stay at rest
• a change in an object's speed and/or direction

Multiple Choice

• the air resistance of the ball
• the force of the ball against the bat

Multiple Choice
