WebUnits of moment. From the formula for the size of the moment, we see that the appropriate units of measuring moments are Nm (newton-metres). A force of 1 N at a perpendicular distance to a pivot of 1 m exerts a moment size of 1 Nm. One Nm is the same as one J (joule), which is a unit of energy. Thus, moments have the same units as energy. WebKinetic Energy Definition. Kinetic energy is the measure of the work an object can do by the virtue of its motion. Kinetic Energy Equation. K E = 1 2 m v 2. Kinetic Energy Units.
