The energy produced in an object due to its position and state is called potential energy. If a spring is pulled and released, it again returns to its previous position. This spring has to be done in a special state. Some energy of the spring is spent in returning the spring to its position, it is potential energy that arises in a particular state or spring of spring. If a spring is pulled and released, it again returns to its previous position. This spring has to be done in a special state. Some energy of the spring is spent in returning the spring to its position, it is potential energy that arises in a particular state or spring of spring. Only the quantity can be shown in it. Let's know more about potential energy.
