Angular displacement refers to the change in the angle of an object as it rotates around a fixed axis.
Angular velocity is the rate at which an object rotates around a fixed axis, measured in radians per second.
Angular acceleration is the rate at which an object's angular velocity changes over time, measured in radians per second squared.
Torque is a measure of how much force causes an object to rotate and is calculated by multiplying force and distance from the axis of rotation.
