Conservation of Energy

States that “energy is neither created nor destroyed but can be converted from one form to another”

Energy use at work

•  power is the rate of doing work

•  work can be explained as a force moving an object in the direction of the force

Formula Work = Force * Distance

Example: if a 230 lb man climbs a flight of stairs 100 ft high

Work = 230lb * 100ft =23000ft/lb

Power – an expression of power is Horse Power hp

33,000 lb a height of 1ft in 1 min. = 1 hp

Electrical Power – the watt W

Watt is the unit of measurement for electrical power 1hp = 746W

Fossil fuel energy can be compared to electrical energy, and one form of energy can be converted to another

1kW = 3413 Btu
