Pushing a child on a swing is easier than pushing an adult on the same swing, because the adult has more inertia.

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

• inertia

• force

• acceleration

• velocity

The force that opposes motion between two surfaces in contact with each other.

• inertia

• friction

• momentum

• gravity

A force that opposes motion between a surface in contact with the atmosphere.

• air resistance

• gravity

• momentum

• terminal velocity

Use Newton's first law of motion to explain why the car stopped when it hit the book.

• Book= balanced force/ Car= change in motion

• Book= balanced force/ Car= constant motion

• Book= unbalanced force/ Car= change in motion

• Book= unbalanced force/ Car= constant motion

The penny on the car represents a passenger in vehicle. How would a seat belt change the motion of a passenger in a collision?

• seat belt= unbalanced force that continues the passenger's motion

• seat belt= unbalanced force that stops the passenger from continuing motion through windshield

• seat belt= balanced force that continues the passenger's motion

• seat belt= balanced force that stops the passenger from continuing motion through windshield

How does the force required to accelerate an object change as the mass increases?

• mass increases, force remains the same

• mass increases, force decreases

• mass increases, force increases

• mass increases, force doubles
