Question

Potential energy is defined

• A. only is conservative fields
• B. as the negative of work done by conservative forces
• C. as the negative of work done by external forces when $\Delta K=0$
• D. All of these

Answer 1

Answer: (D)

All of these

An object can store energy as the result of its position. For example, the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly, a drawn bow is able to store energy as the result of its position. When assuming its usual position (i.e., when not drawn), there is no energy stored in the bow. Yet when its position is altered from its usual equilibrium position, the bow is able to store energy by virtue of its position. This stored energy of position is referred to as potential energy. Potential energy is the stored energy of position possessed by an object.

So from the above explanation , we can clearly say that all the statements are correct.

Hence , option 'D' is correct
