À propos de cette ressource...

The first law of thermodynamics states that energy is neither created nor destroyed. It can, however, be transformed from one form to another. One type of energy that we are most familiar with is kinetic energy, or the energy of movement. Gravitational potential energy is energy due to an object’s position. An object in the air has gravitational potential energy because when released, it will begin to move and convert its stored energy into movement, or kinetic energy. Another example of this is a twisted up rubber band: when you let go of the twists, it moves back to its original form. Mechanical energy is energy that is use to do work, like move objects or power motors. Other forms include thermal energy, which we know as heat, and sound.Energy is measured in Joules, which is equal to 1 kg * m2/s2.ObjectiveChange energy into some of its different forms.
