Answer:

There is a significant difference between work and energy. Work is the transferring of an amount of energy with the help of a force covering a particular distance through a direction. Energy is also referred to as the force which works at a certain distance. These both can be termed as scalar units.

Answer:

Perhaps the simplest way to look at this important question is to treat energy as stored work. or to think of work as energy creation "in progress".

Work can be done by exerting a force through a distance, by applying an external magnetic field to a magnetized spin system, by changing the number of particles experiencing a fixed chemical potential, or by many other processes involving a change in an extensive parameter (like position) under the influence of an intensive one (like a force). There is not just one kind of work.

Similarly, there are many kinds of stored energy: the kinetic energy of a moving mass, the potential energy of a mass elevated in a gravitational field, the chemical energy of hydrogen and oxygen before they react to make water, the electrostatic energy of a charged battery or capacitor, ... the list is endless ... and the ultimate stored energy of mass itself: E = mc^2.

Another feature of energy implied by that famous equation is that it has mass: the charged capacitor is slightly heavier than when it is discharged, although that mass difference is probably too small to measure on any balance. So you can think of work as the creation of mass, if you like; but there is a catch: energy is conserved. When you do work, you have to draw the energy from another source, like the chemical conversion of ATP to ADP in your muscles or the lowering of water from a high reservoir to a low one under the influence of gravity, thereby decreasing the potential energy of said water as you turn the mill wheel to grind grain, leaving behind the least easily utilized form of energy: heat. Heat is less useful because it's disordered. But that's another story....
