Motive Power

In thermodynamics, motive power is an agency, such as water or steam, used to impart motion. Generally, motive power is defined as a natural agent, as water, steam, wind, electricity, etc., used to impart motion to machinery; a motor; a mover. The term may also define something, as a locomotive or a motor, which provides motive power to a system. In current use, motive power may be thought of as a synonym for either "work", i.e. force times distance, or "power", an effect producing motion, depending on the context of the discussion.

Famous quotes containing the words motive and/or power:

    That he delights in the misery of others no man will confess, and yet what other motive can make a father cruel?
    Joseph Addison (1672–1719)

    It is in vain that we would circumscribe the power of one half of our race, and that half by far the most important and influential. If they exert it not for good, they will for evil; if they advance not knowledge, they will perpetuate ignorance. Let women stand where they may in the scale of improvement, their position decides that of the race.
    Frances Wright (1795–1852)
