horsepower
Motor strength measure
Horsepower is a unit measuring the rate at which work is done—the power output of engines, motors, and machines.
One horsepower equals the force needed to lift 550 pounds one foot in one second, roughly the sustained output of a draft horse.
Engine specifications always include horsepower: a 300-horsepower engine.
Figuratively, horsepower suggests raw capability or force: We need more horsepower on this project.
