Work, energy and power are terms that are used regularly but not always correctly. You often hear the word energy being used when power is meant or you hear power being used when force is what is intended. What do we really mean when we talk about a powerful serve in tennis, or a football player's high work rate or a team that is lacking in energy? In Physics the terms work, energy and power have precise meanings. It is important that you are able to use these terms correctly in your Physics examination. You will also be expected to use them in doing calculations and solving problems. You may wish to print a hard copy for your reference.
