Before studying physics, it is easy to confuse terms such as energy, work, power and force. In reality though each of these terms has a very specific and different meaning, and by properly understanding these differences you can begin to better understand (and in many ways), manage energy.

Energy is defined as the potential of a body to do work. There are different forms of energy, these are explained below:

Kinetic energy - This is the energy that it is capable of moving another object by its own movement.

Pressure energy - This is the energy a fluid or gas has due to pressure it is under.

Chemical energy - When chemical reactions occur, energy can be either released or used up.

Electrical energy - When electricity flows, it does work. It is the product of the voltage, current and time taken.

Nuclear energy - Fusion and fission reactions

Thermal energy - Hot items have the ability to do work. Temperature and heat have engineering features the study of which are beyond the scope of this course.


Forces in physics always come in pairs, and the sum of the pair is zero. This is Newton's third law. In other words, for every action - there is an equal and opposite reaction.

Forces act on an object or objects and cause a change in the state of rest, or motion, of the object. For example, a weight of a tractor towing a plough exerts force on the ground as it moves over a paddock; it also exerts force on the plough. The plough, in turn, exerts force on the soil.



When a force is applied to an object and moves that object a certain distance in the direction of the force, the product of the force and the distance moved by the object is known as the Work.


Power is simply the rate at which work is done.

All of these things (and others) can be quantified. You learn to measure them in this course; but even more importantly, you develop a fundamental understanding of the physical world and the dynamics at play between all things, both living and non living.
