What is Dimensional Formula of Torque?

Force causes accelerations and Torque causes angular accelerations.Torque is proportional to the distance between the rotation axis and the point of application of the force (the point at which the force is applied).

Mathematically, Torque is defined as product of Angular acceleration and Moment of Inertia. Its formula is

Torque = Angular Acceleration X Moment of Inertia

Dimensional Formula of Angular Acceleration = M0L0T-2
Dimensional Formula of Moment of Inertia= M1L2T0

Putting these values in above equation we get
Dimensional Formula of Torque= M1L2T-2
SI unit of Torque is N m

What is Dimensional Formula of Angular Velocity?

Angular Velocity is defined as change in angular displacement per unit time. Its formula is

Angular Velocity =Angular displacement/Time
Dimensional Formula of Angular displacement= M0L0T0 Divide it by Time T1

So Dimensional Formula of Angular Velocity = M0L0T-1
SI unit of
Angular Velocity is rad s-1

What is Dimensional Formula of Angular Acceleration?

Angular Acceleration is defined as change in angular velocity per unit time . Its formula is

Angular Acceleration = Angular velocity / Time

Dimensional Formula of Angular velocity = M0L0T-1 Divide it by Time T1

So Dimensional Formula of Angular Acceleration = M0L0T-2
SI unit of
Angular displacement is rad s-2

What is Dimensional Formula of Angular Momentum?

Angular Momentum is a product of Moment of Inertia and Angular Velocity. Its formula is
Angular Momentum = Moment of Inertia X Angular Velocity

Dimensional Formula of Moment of Inertia= M1L2T0
Dimensional Formula of Angular velocity = M0L0T-1

Putting these values in above equation we get

So Dimensional Formula of Angular Momentum = M1L2T-1
SI unit of Angular Momentum is Kg m2 s-1

What is Dimensional Formula of Angular Displacement?

Angular displacement is defined as the ratio of length and radius.

Angular displacement= Length/Radius
Now we know
Dimensional Formula of Length = M0L1T0
Dimensional Formula of Radius  = M0L1T—- Radius is related to length.

So
Angular displacement= M0L1T0/M0L1T0

Hence Dimensional Formula of Angular displacement = M0L0T0
SI units of Angular displacement is radian
