Little do we know we use Work and Energy with almost everything we do without even knowing.
Work: Most people think work, is doing tasks for job or profession for or not for money. But, in Science work is the amount of effort expended when a force causes an object to move a distance. So if your job is to hold a piece of artwork for long amounts of times, you are applying a force, but since the art is not moving you are not technically working. But things like throwing a baseball, work is being done because the force of your arm is moving the ball a distance.
Energy: Most people in the world are familiar with energy, whether their using their own energy or are wasting heat energy. In Science energy is defined as the ability to do work. The metric unit for energy is a Joule (J). Work is done when a force causes a object to move. Therefore energy is the ability to apply a force and move an object. An example is when you are bowling, the bowling ball applies a force to the pins and moves them a distance while knocking the pins down. Since the bowling ball did the work on the pins the rolling ball had the energy.
