Review: Newton's Third Law and Momentum

What is often referred to as the Law of action and reaction?

• Newton's third law of motion

• The law of gravity

According to Newton's third law of motion, for every action, there is:

• An equal and opposite reaction

• A slightly weaker reaction

A book pushes down on a table with a force of 5N, the table..

• Pushes back with a force of 5N

• Does nothing. A table has no force.

The forces in a force pair are the ____ strength.

• Same

• Opposite

The forces two objects apply to each other

• Force Pair

• The Velocity Calculation

The force that is applied first in a force pair

• Force Pair

• Action Force
