Here's a breakdown:
* Newton's Third Law: For every action, there is an equal and opposite reaction.
This means that whenever two bodies interact, they exert forces on each other. These forces are:
* Equal in magnitude: The strength of the force exerted by body A on body B is the same as the force exerted by body B on body A.
* Opposite in direction: The forces act in opposite directions along the same line of action.
Examples:
* Walking: You push on the ground with your feet (action), and the ground pushes back on your feet (reaction) propelling you forward.
* Swimming: You push water backward with your arms and legs (action), and the water pushes you forward (reaction).
* Rocket Launch: The rocket expels hot gas downward (action), and the gas pushes the rocket upward (reaction).
* Collision: When two cars collide, they exert equal and opposite forces on each other.
Important Note: The forces described in Newton's Third Law always act on *different* bodies. You cannot apply the Third Law to the forces acting on the *same* body.
