A fundamental mechanical quantity measuring how fast a system can apply force to move a load. In linear systems, it equals force multiplied by velocity. In rotating machinery, it is calculated as torque multiplied by angular velocity. Engineers size motors, engines, and gearboxes based on their ability to deliver the necessary power to keep a machine running at its design speed under load.

We're dropping RPMs under heavy load because the drive motor lacks the power to push through the friction.
