- Everything contains energy including all forms of matter and so all objects.
- Energy is evident in all forms of movement, interaction, and changes to the forms and properties of matter.
- Energy can exist in different forms, including thermal energy, chemical energy, electrical energy, and nuclear energy.
- At an atomic level, energy is evident in the motion of electrons orbiting the nucleus of atoms.
- Energy is stored in the nucleus of atoms as a result of the binding forces between protons and neutrons.
- Energy can be transferred from one object to another and converted between different forms, but it cannot be created or destroyed.
- Everything in the universe uses energy of one form or another all the time.
- Light has energy but no mass, does not occupy space and has no volume.
- Energy is often described as potential energy or kinetic energy.
- Energy is measured in joules whilst power is measured in joules per second.
