Angular Displacement
The change in angle through which a body rotates relative to a fixed point.
Angular Velocity
The rate of change of angular displacement with respect to time
Angular Acceleration
The rate of change of angular velocity with respect to time
Torque
The change in rotational motion due to a turning force
Inertia
The resistance to a change in motion
Moment of Inertia
The resistance to a change of rotational motion, depending on the distribution of mass around a chosen axis of rotation
Conservation of Angular Momentum
The angular momentum of a system always remains constant, unless a net torque is acting on the system
Angular Impulse
An average resultant torque acting for a time t produces a change in angular momentum
Torque of a Couple
The sum of the moments produced by each of the forces in a couple of
Isothermal process
A process where no change in temperature occurs
Adiabatic process
No heat energy is transferred into or out of the system
