Flywheel disk or hoop physics
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. WebLooking at the equation: Kr = (1/2) * m * r^2 * ω^2. Without the summation portion this is the rotational kinetic energy of a small piece of the object. The term r is not the radius of the whole object. It is the distance of the small part of the object we are looking at is away from the axis of rotation.
