Energy is the ability to do work or cause a change. It can't be created or destroyed, it just changes form. Energy transfers and transformations happen when energy moves from one place or form to another. Energy can be transferred through sound, light, heat, electricity, and more.

Energy Transfer: The process of transferring energy from one system to another. Energy Transformation: The process of changing the form of energy, from one form to another. Energy Conservation: The process of conserving energy so that it can be used again in the future.

The total amount of energy in a system does not change, even when it is transferred from one object to another or transformed from one form to another. Energy can be transferred from one object to another through heat, light, sound, electrical currents, and mechanical processes. Energy is always conserved, even when it is converted from one form to another, such as when it is converted from potential energy to kinetic energy.
