Question

If L is angular momentum of rotating body and E is its rotational kinetic energy then......​

Answer 1

Answer:

Rotational kinetic energy can be expressed as: Erotational=12Iω2 E rotational = 1 2 I ω 2 where ω is the angular velocity and I is the moment of inertia around the axis of rotation. ... There is a close relationship between the result for rotational energy and the energy held by linear (or translational) motion.

Answer 2

Concept:

• Rotational motion
• Angular momentum
• The rotating equivalent of linear momentum is angular momentum
• The moment of inertia
• The moment of inertia is a unit of measurement for the resistance a body exhibits to having the speed of its rotation about an axis changed by the application of torque.

Given:

• The angular momentum = L
• The rotational kinetic energy = E

Find:

• The rotational kinetic energy in terms of angular momentum

Solution:

L = mvr = mwr^2 (w = angular velocity)

E = 1/2 I w^2  (I = moment of inertia)

I = L/w

E = 1/2 L/w (w)^2

E = 1/2 Lw

The rotational kinetic energy is directly proportional to the angular momentum.
