deduse the expression for rotational kinetic energy |
| Answer» Dffrr<br>The expression for rigid body’s “rotational kinetic energy” is\xa0SOLUTION:A body undergoing a rotational dynamics with angular velocity ω will also poses a translational motion. Let the velocity for translation motion be ‘’v’’.We know for translational motion the energy poses by body is kinetic and given asAlso we know that for a body obeying rotation v=rωSubstituting in translationAlso there is a relation for moment of inertia i.e\xa0Substituting we get,\xa0 | |
