What is the relationship between work and potential energy?

Click For Summary
SUMMARY

The relationship between work and potential energy is defined by the equations Work = ∫Fdx and Potential Energy, U = -∫Fdx. This establishes that work done on an object is equal to the negative change in potential energy, expressed as W = -ΔU. Furthermore, for conservative forces, the relationship is clarified by the equation F = grad(W), indicating that the force can be derived from the gradient of the work function. This discussion highlights the fundamental principles of energy conservation in physics.

Potential energy is stored energy. It is the energy that an object possesses due to its position in a force field or due to its configuration. Potential energy is the energy that an object possesses due to its position in a force field or due to its configuration.
