Question

find an expression for the rotational kinetic energy possesed by a body?​

Answer 1

Answer:

The Formula for Rotational Energy

Linear kinetic energy = ½ * m * v2.

I = m*r2, where I is the moment of inertia, m is the mass of the body and r is the distance of point mass from the rotational axis. ...

K.Erotational = ½ (I * ω2). ...

K.E.total = K.E.rotational + K.E.linear = ½ (I * ω2) + (½ * m * v2)

Answer 2

Answer:

1) Linear kinetic energy = ½ * m * v2.

2) I = m*r2, where I is the moment of inertia, m is the mass of the body and r is the distance of point mass from the rotational axis.

3) K.Erotational = ½ (I * ω2).

4) K.E.total = K.E.rotational + K.E.linear = ½ (I * ω2) + (½ * m * v2)
