Questions & Step-by-Step Solutions
If a rotating object has an angular momentum of 20 kg·m²/s and a moment of inertia of 4 kg·m², what is its angular velocity?
Angular Momentum – Angular momentum (L) is the product of moment of inertia (I) and angular velocity (ω), represented by the formula L = Iω.
Moment of Inertia – Moment of inertia (I) is a measure of an object's resistance to changes in its rotation, depending on the mass distribution relative to the axis of rotation.
Angular Velocity – Angular velocity (ω) is the rate of rotation of an object, typically measured in radians per second.
