Newtons 3rd Law and Force Pairs

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What do we mean by 'force pairs'?

Back

Forces that two objects exert on each other, which are equal in magnitude and opposite in direction.

Front

What unit is used to measure force?

Back

Newton (N) is the unit used to measure force.

Front

If two objects collide, what can we say about the forces they exert on each other?

Back

They exert equal and opposite forces on each other.

Front

True or False: All forces occur in pairs.

Back

True.

Front

What happens when a person jumps off a diving board?

Back

The person exerts a downward force on the board, and the board exerts an equal upward force on the person.

Front

What is an example of Newton's Third Law in sports?

Back

When a player kicks a ball, the ball exerts an equal and opposite force back on the player's foot.

Front

What is the relationship between mass and force in Newton's Second Law?

Back

Force equals mass times acceleration (F = ma).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is an example of a force pair in everyday life?

Back

When you push against a wall, the wall pushes back against you with equal force.
