Force, in newtons, times distance, in meters, is work and energy {energy measurement} in joules (J), in MKS system. Force, in dynes, times distance, in centimeters, is energy unit {erg} in CGS system. 10000 erg equals 1 joule.
In English measure, force is weight, in pounds, times distance, in feet {foot-pound}.
electric
Voltage, in volts, times charge, in coulombs, is electric energy in joules. For subatomic particles, electric energy is voltage, in volts, times electron charge {electron-volt} (eV). Electric energy is power, in kilowatts, times time, in hours {kilowatt-hour}. USA houses use hundreds of kilowatts each month.
heat
Heat energy is energy needed to heat one gram of water one degree Celsius {calorie} (cal) or one kilogram of water one degree Celsius {Calorie} (Cal). 1 Cal = 1000 cal. In English measure, heat energy uses larger units {British thermal unit} (BTU).
