Question

In the formula for the change in potential energy, \[\vec F\] · d\[\vec x\] = dU, what does the term \[\vec F\] represent?

पर्याय

• External force applied

• Conservative force (like gravity)

• Friction force

• Net accelerating force

Answer 1

External force applied

Explanation:

 

The change in potential energy is equal to the work done on the system by an external force to change its configuration.
