Law of rotational inertia
Web30 sep. 2024 · Newton’s second law in linear motion has a rotational counterpart, referred to as Newton’s second law of rotation. What does rotational inertia depend on? Rotational inertia depends both on an object’s mass and how the … A quantity related to inertia is rotational inertia (→ moment of inertia), the property that a rotating rigid body maintains its state of uniform rotational motion. Its angular momentum remains unchanged unless an external torque is applied; this is called conservation of angular momentum. Rotational inertia is often considered in relation to a rigid body. For example, a gyroscope uses the property that it resists any change in the axis of rotation.
