Newton's second law relates mass and acceleration to force. What is a force?

• A push or a pull.

• An action that makes an object move.

• An action that works against motion.

• A power to be reckoned with.

Based on the picture, how would you describe the motion of the box?

• The forces are unbalanced, so the box would move to the right.

• The forces are balanced, so the box will not move.

• The forces are unbalanced, so the box will not move.

• The forces are balanced, so the box will move to the right.

With unbalanced forces, the object will move in the direction of the:

• larger force

• smaller force

• equal force

According to Newton’s first law of motion, a moving object that is acted on by a balanced force will:

• remain in motion

• eventually come to a stop

• stay at rest

• accelerate (speed up)

A person bought coffee and put it on the seat next to them in their car. If they stopped quickly and the coffee spilled, which of Newton's laws would that represent?
