In physics, energy is a property of objects which can be transferred to other objects or converted into different forms.

Many forms of energy

Energy has many different forms, making a comprehensive definition difficult.

One common definition: energy is the ability of a system to perform work.

In SI units, energy is measured in joules, the energy transferred to an object by the mechanical work of moving it 1 metre against a force of 1 newton.

Conversion

All of the many forms of energy are convertible to other kinds of energy, and obey the conservation of energy.
