Newton’s Third Law 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 will exert an equal force in the opposite direction. In everyday life, this can be seen when we walk, push a door, or even when we sit on a chair – the force we exert on the ground or the chair is met with an equal and opposite force.
A classic example of Newton’s Third Law is the recoil of a gun. When a bullet is fired from a gun, the gun exerts a force on the bullet, propelling it forward. At the same time, the bullet exerts an equal force on the gun in the opposite direction, causing the gun to recoil.
Yes, Newton’s Third Law is a fundamental principle in physics and is always true. It applies to all types of forces – gravitational, electromagnetic, and mechanical – and works in both directions.
Newtons’s Third Law is closely related to the conservation of momentum, which states that the total momentum of a closed system remains constant. This means that the amount of momentum lost by one object due to an action must be gained by another object in the opposite direction due to the reaction, keeping the total momentum of the system the same.
Yes, Newton’s Third Law can be used to explain gravitational forces. According to the law, every object exerts a gravitational force on every other object. This means that when an object exerts a force on the Earth, the Earth exerts an equal and opposite force on the object, keeping both objects in orbit around each other.
