## Is mathematics used in physics to describe work and energy? |

Yes, mathematical equations can be used to describe work and energy. Energy comes in many forms, but its basic definition is in terms of work. Work is done when a force moves a body a certain distance. It is expressed in the simple equation: *W = Fd*, in which *W* is work, *F* is the force, and *d* is the distance. In this definition, only force in the direction of the object’s motion counts.
