Web3 mrt. 2024 · A object in motion or particle has kinetic energy, which relies on both its mass and its rate of motion. Any combination of movements, including translation, rotation along an axis, and vibration, may constitute the kind of motion. kinetic energy= ½mv² v =4m/s m= 2000kg KE = ½ (2000) (4)² = 16000 Joules
WebLaw of Conservation of Angular Momentum. The angular momentum of a system of particles around a point in a fixed inertial reference frame is conserved if there is no net external torque around that point: d→L dt = 0 d L → d t = 0. or. →L = →l 1 +→l 2+⋯+→l N = constant.
