Equation for rotational kinetic energy
WebThis is an important new term for rotational motion. This quantity is called the moment of inertia I, with units of kg⋅ m2 kg · m 2: I = ∑jmjr2 j. I = ∑ j m j r j 2. For now, we leave the expression in summation form, representing the moment of inertia of a system of point particles rotating about a fixed axis. Websource. Like potential energy, kinetic energy has two primary types: in this case, translational kinetic energy and rotational kinetic energy. The translational kinetic energy of an object is the amount of work it requires to take that object from its resting position to a required velocity, e.g., accelerating a parked car to 50 miles per hour. . …
