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.
In physics, power is the rate of doing work, the amount of energy transferred per unit time. Having no direction, it is a scalar quantity. In the International System of Units, the unit of power is the joule per second, known as the watt in honour of James Watt, the eighteenth-century developer of the steam engine condenser. Another common and traditional measure is horsepower. Being the rate of work, the equation for power can be written: power = work time {\displaystyle {\text{power}}={\frac {
