Question

Derive an expression for rotating kinetic energy of rigid body/

Answer 1

Answer:

GOOD MORNING HAVE A GREAT DAY ❤

Explanation:

The rotational kinetic energy is thekinetic energy of rotation of a rotating rigid body or system of particles, and is given by K=12Iω2 K = 1 2 I ω 2 , where I is the moment of inertia, or “rotational mass” of the rigid body or system of particles.

Answer 2

Consider a rigid body rotating with a constant angular velocity

ω

about an axis passing through the point O.

As the body rotates, all the particles perform uniform circular motion.
