## Rotational Kinetic Energy: Definition Formula Unit

The kinetic energy generated by an object’s rotation, also known as angular kinetic energy, is a part of its whole kinetic energy. Its formula is Erot = (1/2)Iω^2 and unit is Joule in SI.

## Moment of Inertia – Definition Unit Formula Concept

Definition of Moment of Inertia: The sum of the products of the mass of each particle in the body with the square of its distance from the axis of rotation expresses a body’s tendency to resist angular acceleration. Unit is kg m^2. Dimension [ML^2].

## Torque: Definition Concept Unit Formula

Torque: Torque is the product of force and moment arm. It is a vector quantity. The unit of torque is Newton-meter (N-m)

## Moment of Force: Definition Formula Unit Concept

If forces act on a finite size body they may produce a turning effect. This effect is measured by the moment of the force. This is distinct from a body’s tendency to move or translate in the force’s direction. Its unit is N-m.

## Angular Acceleration: Formula Concept Unit

Angular acceleration: The time rate of change of angular velocity. The common unit is angle per second squared.

## Angular Velocity: Definition Unit Formula Concept

The rate of rotation of an object or a particle around a centre or a specified point in a given time period is called angular velocity. Angular Velocity Theory concept example unit dimension and formula for classes 9 10 11 and 12.
