Work, Energy, and Power. Our Work, Energy, and Power unit represents an effort to present a model of energy as a tool for analyzing the motion of an object. The model relies on the confidence that energy can be kept track of; and because it can, we are able to make predictions of how fast an object will move, how hight it will go, and how far ...
26 maj 2016 · Today, you learned the two equations we can use to describe work, and that energy is the ability to do work. We also talked about kinetic and potential energy, and how they play into non ...
Physicists define work as the amount of energy transferred by a force. Learn about the formula for calculating work, and how this relates to the work-energy principle, which states that the net work done on an object is equal to the change in its kinetic energy.
