Question

state the dimension and SI unit of angular momentum​

Answer 1

Answer:

Appropriate MKS or SI units for angular momentum are kilogram metres squared per second (kg-m2/sec). For a given object or system isolated from external forces, the total angular momentum is a constant, a fact that is known as the law of conservation of angular momentum.

Answer 2

The dimension and SI unit of angular momentum is explained below:

• Angular momentum is the momentum possessed by the rotating bodies and it is an analog of rotational momentum in terms of some of its properties.
• The formula of angular momentum is:
• $l = mvr$
• l is angular momentum, m is the mass, v is the velocity and r is the radius of the rotating body.
• Linear momentum is the product of mass and velocity. which means angular momentum is the product of the radius times the linear momentum.
• Now, the Dimensions of angular momentum = $M{L}^{2} {T}^{ - 1}$
• The SI unit of angular momentum is $kg {m}^{2} {s}^{ - 1}$
