Question

what is change in potential energy​

Answer 1

Explanation:

As we know, an object can store energy as a result of its position. In the case of a bow and an arrow, when the bow is drawn, it stores some amount of energy, which is responsible for the kinetic energy it gains, when released. We can define potential energy as:

The energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.

Similarly, in the case of a spring, when it is displaced from its equilibrium position, it gains some amount of energy which we observe in the form of stress we feel in our hand upon stretching it. We can define potential energy as a form of energy that results from the alteration of its position or state.

Answer 2

Answer -

• The change in potential is then defined as the negative of the work done by that force. This is technically the gravitational potential energy of the ball-Earth system. For internal forces (like gravity) in a system, you will have a potential energy term.
