WebNov 3, 2011 · The rotation state of the wheel changes as you accelerate the car, so the moment of inertia of the wheels is relevant, in addition to their mass. For the case of the hoop, the kinetic energy is. K = 1 2 m v c m 2 + 1 2 I ω 2. where I is the moment of inertia for rotations about the center of the hoop and ω is the angular velocity. 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.
