energy is defined as the ability to do....work.
It is a usable source of power.
Energy is the property of a substance or a system which enables it to do work. Energy and work have the same units, Joules in the SI system. When you do work you are using energy, and if the work stores energy, this energy is then available to do future work, this is called potential energy. The simplest definition of energy or work is that 1 Joule is the work done by a force of 1 Newton acting over a distance of 1 meter. Thermal energy can be related to mechanical energy by the equivalent that 1 calorie = 4.2 Joules, this is called the mechanical equivalent of heat.

Energy is the capacity of an object to perform work.
Energy is simply defined as the ability to do work.
Energy is the ability to do work or cause change. Energy is stored in the cells in the structures of molecules of substances such as carbohydrates, lipids, and proteins.
In science, 'energy' is the ability of matter to overcome inertia and perform work.
Energy is the capability of doing work
In Physics it is a Machine that has the capability to Perform WORK on an Object.

Potential energy can be defined as the ability to do work.
First, let's define energy; plain old vanilla energy. Energy is a capability. It's a capability to do work or cause a change. In other words things that have energy can do work. Like if you have energy you can tidy up your room, which is doing work. There are all sorts of energy sources. One of those sources is motion. A waterfall. for example, has the capability to do work (i.e., it has energy) because that water is in fact falling. It's moving. And when anything has the capability to do work because it's moving that capability is called kinetic energy. Mass cannot do work or cause a change. It is not energy. So there's a major difference. One is energy the other is not. Mass at some level of quantity can be touched. It is tangible. Energy is not tangible; it's only a capability. Mass is a measure for the inertia of an object. NOTE: You've probably read about E = mc^2 and the term mass.energy. Some interpret that as meaning mass is energy. It is not energy. It is the potential for producing energy, but it's not energy itself because mass cannot do work or cause a change.
Energy is often defined as the potential for doing work

Energy is the capacity of an object to perform work.
It is what will need to perform work! The cell in our body need nutrient and energy to perform wook
Energy is the ability to do work. Force is something that changes motion.
