Energy is defined as the ability to do work. Energy can be found in many things and can take different forms. For example, kinetic energy is the energy of motion, and potential energy is energy due to an object's position or structure. Energy is never lost, but it can be converted from one form to another.

Light and the electromagnetic radiation spectrum. Wave and particle-like behaviour, and how to calculate the wavelength or frequency of a light wave.

The potential energy between two objects due to long-distance forces can be thought of as being stored in a field. When the objects move due to the field forces, the energy stored in the field decreases

This video explains how to round decimals.
