A.4.2 Moment of inertia (HL only) Key Definitions

Definition

Inertia

Inertia is the tendency of an object to resist changes in its state of motion.

Definition

Rigid body

A rigid body is an idealized object in which the relative positions of all particles remain fixed, regardless of external forces or torques.

Definition

Rotational kinetic energy

Rotational kinetic energy or angular kinetic energy is kinetic energy due to the rotation of an object and is part of its total kinetic energy.
