The third law states that for every action in nature(force)there is an equal and opposite reaction.

Newton's Third Law of Motion

Newton's third law of motion states that for every action, there is an equal and opposite reaction. This means that whenever an object exerts a force on another object, the second object exerts an equal and opposite force on the first object.

Explanation

This law is based on the principle that forces always come in pairs. These forces are called action and reaction forces. The action force is the force exerted by one object on another, while the reaction force is the force exerted by the second object on the first object.

For example, when you push a book across a table, the action force is the force you exert on the book, and the reaction force is the force the book exerts on your hand. The two forces are equal in magnitude but opposite in direction.

Another example is the firing of a gun. When a bullet is fired from a gun, the gun recoils backward due to the reaction force of the bullet leaving the gun.

Importance

Newton's third law of motion is important because it helps us understand how objects interact with each other. It is applicable in many different situations, from everyday life to space travel. Without this law, it would be difficult to explain why objects move the way they do.

Conclusion

In conclusion, Newton's third law of motion is a fundamental principle of physics that states that every action has an equal and opposite reaction. This law helps us understand the forces that are involved in the interactions between objects, and it is an essential concept for anyone studying physics.
