Angular Kinetics

  • Duane Knudson


Angular kinetics explains the causes of rotary motion and employs many variables similar to the ones discussed in the previous chapter on linear kinetics. In fact, Newton’s laws have angular analogues that explain how torques create rotation. The net torque acting on an object creates an angular acceleration inversely proportional to the angular inertia called the moment of inertia. Angular kinetics is quite useful because it explains the causes of joint rotations and provides a quantitative way to determine the center of gravity of the human body. The application of angular kinetics is illustrated with the principles of Inertia and Balance.
