Question
Write the main characteristics of potential energy
✓
Answer
(i) Potential energy is a scalar function of position. (ii) The negative value of the derivative of potential energy with respect to position determines the force $\overrightarrow{F}=-\frac{d}{d t} U_{(x)}$ (iii) The value of potential energy depends on the frame of reference. (iv) The concept of potential energy is defined only for internal conservative forces and not for non-conservative forces. (v) Change in potential energy continous during the motion of a rigid object because the distance between its particles doesn't change even when external force is applied to the motion of a rigid object.
