Here's the statement of Newton's Third Law:

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

Here's what that means:

* Action and Reaction: Whenever one object exerts a force on a second object (the action), the second object exerts an equal and opposite force back on the first object (the reaction).

* Equal in Magnitude: The forces are equal in strength, meaning they have the same amount of force.

* Opposite in Direction: The forces act in opposite directions.

Examples:

* Jumping: When you jump, you push down on the ground with your feet (action). The ground pushes back up on you with an equal and opposite force, propelling you upwards.

* Rocket Launch: A rocket engine expels hot gases downwards (action). The gases exert an equal and opposite force upwards on the rocket, causing it to lift off.

* Swimming: When you push water backwards with your arms and legs (action), the water pushes you forward with an equal and opposite force.

Key points:

* The action and reaction forces always act on different objects.

* These forces occur simultaneously.

* Newton's Third Law is fundamental to understanding how forces interact in the universe.
