It is also known as biogenesis, reproduction, or procreation in the biological sciences. Generation is also often used synonymously with cohort in social science; under this formulation it means people within a delineated population who experience the same significant events within a given period of time.
Power in physics is the amount of work done divided by the time it takes, or the rate of work. Hereâs what that looks like in equation form: Assume you have two speedboats of equal mass, and you want to know which one will get you up to a speed of 120 miles per hour faster.
And yet, power just means energy flow per unit time. We all know the Watt is a unit of power consumption and have an idea how quickly a 1500 Watt kettle boils water. The unit of energy is the Joule - a Watt is just a flow of one Joule per second. The other popular unit of power is the horsepower. The conversion is that one horsepower = 756 Watts. A 100-HP car would be able to turn a 75,600 - Watt electrical generator, or 75.6 kilowatts. So anybody who does talk about energy, rarely speaks in Joules.
