Why is the Integral of Force Over dx Equal to Kinetic Energy?

Click For Summary
SUMMARY

The integral of force over displacement (dx) is equal to the change in kinetic energy, as established by the work-energy theorem. This theorem states that the work done by the net force acting on an object is equal to the change in its kinetic energy. Specifically, if F represents the force and dx represents the infinitesimal displacement, the integral ∫F dx yields the work done, which directly correlates to the kinetic energy gained by the object.

PREREQUISITES
  • Understanding of Newton's Second Law of Motion
