This is the best video I have come across so far that is used to introduce the idea of perpetual motion engines and why it violates the principle of conservation of energy.

This GeoGebra app allows users to change the magnitude and direction of the force acting on an object, as well as the initial velocity.
The change in kinetic energy is calculated along with the work done in the direction of the force.
This demonstrates a very important concept in Physics known as the Work-Energy Theorem, where the net work done on a particle equals to its change in kinetic energy.
