Front

What is the law that states for every action, there is an equal and opposite reaction?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction.

Front

What do we call a force that does not cause a change in motion?

Back

A Balanced Force is a force that does not cause a change in the motion of an object.

Front

What is the term for the resistance of an object to change its motion?

Back

Inertia is the resistance of an object to any change in its motion.

Front

What is the effect of an unbalanced force on an object?

Back

An unbalanced force causes an object to accelerate or change its motion.
