Horsepower

A unit of power equivalent to 746 watts, often used to measure engine power.

Work

Done on an object when it moves in the same direction as the applied force.

Formula for Power

Power = Work / Time or Power = Force x Distance / Time.

Unit of Work

The SI unit for work is Joules.

No motion = no work

Work is not done if there is no motion of the object.

Calculating Work

Work can be calculated using the formula W = Force x Distance.

Units of Force

Force is measured in Newtons.

Units of Distance

Distance is measured in Meters or Kilometers.
