Newton's Third Law of Motion

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the net force?

Back

The combination of all the forces acting on an object.

Front

What does Newton's Third Law imply about forces?

Back

Forces always occur in pairs; if one object exerts a force on another, the second object exerts a force of equal magnitude and opposite direction on the first.

Front

What is another name for Newton's Third Law?

Back

The Law of Action and Reaction.

If you push against a wall, what does the wall do?

Back

The wall pushes back against you with an equal force.

Front

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

Back

When you jump off a small boat, you push the boat backward as you move forward.

Front

How does Newton's Third Law apply to walking?

Back

When you push your foot backward against the ground, the ground pushes you forward.

Front

What is the difference between action and reaction forces?

Back

Action forces are the initial forces applied, while reaction forces are the forces that respond to the action.

Front

What happens to the net force if two equal forces act in opposite directions?

Back

The net force is zero.

Front

How can you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their directions.
