newton's third law

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

For example, if you push against a wall with a certain force, the wall pushes back against you with an equal force in the opposite direction. Another example is when you jump off a boat, the boat moves backwards because you applied a force on it, and it applies an equal and opposite force on you, propelling you forward.

This law is important in understanding how forces interact and how motion occurs. It helps explain phenomena such as walking, swimming, and the launch of a rocket. Without Newton's third law, objects would not be able to move or interact with each other.
