Flywheel disk or hoop physics
WebNewton’s 2nd law relates force to acceleration. In the angular version of Newton’s 2nd law, torque \tau τ takes the place of force and rotational inertia takes the place of mass. When the rotational inertia of an object is constant, the angular acceleration is proportional to torque. For example, if we attach a rotating disc to a massless ...

WebSep 12, 2024 · We can apply the definition of power derived in Power to rotational motion. From Work and Kinetic Energy, the instantaneous power (or just power) is defined as the rate of doing work, P = dW dt. If we have a constant net torque, Equation 10.8.4 becomes W = τθ and the power is. P = dW dt = d dt(τθ) = τdθ dt. WebAug 21, 2007 · If you are using MKS (standard metric) units, E will be in joules, m will be the mass of the flywheel in kg, r will be the radius of the flywheel in meters, and w will be the angular velocity in radians/second. To convert rpm to radians per second, you'd take (revolutions / minute) x (2 pi radians / revolution) x (1 minute) / (60 seconds)
