Answer:
The kinetic energy (K.E.) of a rigid body is the energy possessed by the body due to its motion. It is defined as the energy that an object has due to its motion and is equal to one-half the product of the object's mass and the square of its velocity.
For a rigid body that is moving with translational motion, the kinetic energy is given by:
K.E. = (1/2)mv^2
where m is the mass of the rigid body, and v is its velocity.
For a rigid body that is rotating about a fixed axis, the kinetic energy is given by:
K.E. = (1/2)Iω^2
where I is the moment of inertia of the rigid body about the axis of rotation, and ω is its angular velocity.
In general, the kinetic energy of a rigid body depends on both its translational and rotational motions. It can be calculated by summing the kinetic energy due to both types of motion:
K.E. = (1/2)mv^2 + (1/2)Iω^2
where m is the mass of the body, v is its velocity, I is its moment of inertia, and ω is its angular velocity.
