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 principle of conservation of energy states that energy is neither created nor destroyed, it is just transformed from some types of energy into others. The following visual will help you to understand what is meant by the principle of conservation of energy when a body falls.

The theorem of conservation of mechanical energy states that the work carried out on a body is invested exactly in increasing some type of energy. The visual simulates a moving train.

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.
