SPH3U: Work and Energy
... The gravitational potential energy of an object of mass, m, located at a vertical position, h, above a reference position is given by the expression, Eg =mgh. The reference position is a vertical position that we choose to help us compare gravitational potential energies. At the reference position, ...

... In the United States, we customarily rate engines in units of _________________ and electricity in ___________, but either may be used. In the metric system of units, automobiles are rated in kilowatts. One horsepower (hp) is the same as 0.75 kW, so an engine rated at 134 hp is a 100-kW engine. ...
