Physics question

[Hitman]

Wonder why its called "horse power", and not "donkey power" or "cow power"... Maybe 1 horse power is equal to 2 donkey powers...?:hmm:

Was about to explain it myself, but why bother writing.....http://en.wikipedia.org/wiki/Horse_p...2horsepower.22

My elder son says his baby-cart has 1 "dad" power

A Newton is a unit of force, now power. For power you need to use

Newton meters/second

Well said Bill!

Strength or force in engines is TORQUE, torque over time is POWER
