Speed is equal to 

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

Two equal forces acting in opposite directions on an object

• Inertia

• Balanced Force

• Push

• Unbalanced Force

An unequal push/pull on an object that causes a change in motion:

• Unbalanced Force

• Push

• Balanced Force

• Inertia

The tendency for an object's motion to remain unchanged:

• Newton's 3rd Law

• Unbalanced Force

• Gravity

• Inertia

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

Which of these is an example of Newton's First Law, inertia?

• pushing against a brick wall, and the brick wall does not move
• pushing against a stationary wheelbarrow, and the wheelbarrow accelerates forward
• pushing a wheelbarrow full of bricks, and the bricks slide back toward the handles
• pushing a wagon to the top of a hill, and the wagon to the top of hill and the wagon accelerates down the hill without assistance
