Power Absorbed by Disc Brake Formula

What do you mean by power absorbed by the disc brake?

The energy absorbed by a brake depends upon the type of motion of the moving body. The motion of a body may be either pure translation or pure rotation or a combination of both translation and rotation. The energy corresponding to these motions is kinetic energy. Disc brake systems provide superior stopping power to drum brake systems, due in large part to a disc brake system's ability to dissipate heat more efficiently than drum brakes.
