Flywheel angular momentum
WebRotational inertia is a property of any object which can be rotated. It is a scalar value which tells us how difficult it is to change the rotational velocity of the object around a given rotational axis. Rotational inertia … Webr, start subscript, \perp, end subscript. is the perpendicular radius from a chosen axis to the mass's line of motion. Angular momentum of an object with linear momentum is proportional to mass, linear velocity, and perpendicular radius from an axis to the line of the object's motion. Δ L = τ Δ t. \Delta L=\tau \Delta t ΔL = τ Δt.
