What is a PUSH or PULL of an object?

• Motion
• Force
• Friction
• Gravity

Which force causes a change in motion?

• unbalanced force

• balanced force

• gravitational force

• frictional force

Speed is equal to 

• Distance/Time
• Time/Distance
• Time x Distance
• Acceleration

What is the unit to measure force?

"For every action, there is an equal and opposite reaction."

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• Newton's 4th Law

Force = Mass x Acceleration

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• Newton's 4th Law

Newton’s first law of motion is also called the law of ________?

• Mass
• Inertia
• Force
• Velocity

Slamming on the brakes in a moving car makes a passenger move forward against his or her seat belt because

• the passenger has the inertia to keep moving forward
• the passenger is being pushed by the seats of the car
• the passenger is better able to stop themselves in this manner
• the passenger has an equal and opposite force supporting their weight

How long will an object remain at rest, according to Newton's First Law of Motion?

• it can't rest
• until noon
• until an unbalanced force occurs
• as long as there are unbalanced forces acting on it 

You are in a stationary car that accelerates. Your body is pushed back. Explain.

• newtons

• vector

• inertia

• gravity
