Newton's 3rd Law of Motion

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is an unbalanced force?

Back

A force that causes an object to change its motion.

Front

What happens when forces are balanced?

Back

The object remains stationary or continues to move at a constant speed.

Front

What is an example of Newton's 3rd Law?

Back

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

Front

What is the reaction force when a swimmer pushes the water backwards?

Back

The water pushes the swimmer forward.

Front

What does 'equal and opposite' mean in Newton's 3rd Law?

Back

For every force exerted, there is a force of the same strength acting in the opposite direction.

Front

What is the role of frictional force?

Back

Friction opposes the motion of an object.

Front

How does gravity relate to Newton's 3rd Law?

Back

Gravity pulls objects down, and objects exert an equal force upwards.

Front

What is an example of balanced forces?

Back

A book resting on a table has balanced forces acting on it.

Front

What happens to an object in motion if no unbalanced forces act on it?

Back

It continues to move at a constant velocity.
