I suggest you read the Wikipedia article on "energy". There is really no definition of "energy" that's short, easy to understand, and accurate; the reason for this is that "energy" is a fairly complex concept. You might say that it's a magnitude in physics that is conserved - you can't increase or decrease the total amount of energy. However, note that there are several other magnitudes in physics that are also conserved.
they define when work occurs energy. Energy is the ability to do work.
The definition of energy is the ability to work.
*A+*energy

yes
Matter occupies space and has mass Explain how energy must be described in terms of these two factors Then define energy?
Total amount of kinetic energy and potential energy of all the particles in a substance.

To apply energy to do something.
A joule, a Calorie...
Scientists define energy as the ability to do work or cause a change. It can exist in various forms such as kinetic, potential, thermal, or electromagnetic energy. Energy cannot be created or destroyed, but only transformed from one form to another.
Energy is hard to define because it comes in various forms and can be transferred or transformed in many ways. Additionally, energy is a concept that is used to describe the capacity of a system to do work or produce heat, making it abstract and difficult to pin down with a single, universally agreed upon definition.
