Work is one of the ways of transmitting energy between bodies. The following visual will help you understand the concept of work by modifying the force and the angle which it forms with the horizontal. Click on help to see the possibilities it offers.

The educational resource shows a visual about the conservation of energy: the sum of the kinetic energy and the potential energy of a body (mechanical energy) remains constant, provided there are no forces of friction.

The educational resource shows an interactive animation about the heat: heat is the transference of energy from one body to another.
