WebBy itself, this force must NOT be doing any work upon the object. A force acts upon an object at a 90-degree angle to the direction that it is moving. This force is doing negative work upon the object. An individual force does NOT do positive work upon an object if the object is moving at constant speed. An object is moving to the right. WebEnergy is a measurement of the ability of something to do work. It is not a material substance. Energy can be stored and measured in many forms. Although we often hear people talking about energy consumption, energy is never really destroyed. It is just transferred from one form to another, doing work in the process.
