At one competition car suspension book point, the horse accelerates the sleigh with you on it, with a combined mass of 500 kilograms, from.0 meter/second.0 meters/second.0 seconds.This conflict isnt serious, however, because one symbol is for units (watts) and one is for a concept (work).Power times time energy (more) next.Sometimes, it isnt just the amount of work you do but the rate at which you do work thats important.Answered, in, in physics, Power is equal to Work divided first drop of crimson audiobook by time: P W/t P Power W Work t time.
What would you like to do?
Power times time energy.
Education, science, physics, how to Calculate Power Based on Work and Time.
In physics, the concept of power gives you an idea of how much work you can expect in a certain amount of time.
Say, for example, that youre in a horse-drawn sleigh on the way to your grandmothers house.Answered, in, yes, power is equal to work divided by time, or the average power is the amount of energy converted divided by the time the transfer takes.If one boat takes three weeks to get you up to 120 miles per hour, that may not be the one you take to the races.Answered, in, the definition of work is (force) times (distance).This means that multiplying power by time leaves Joules, or energy.Heres 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.Plugging in the numbers gives you.Ignoring silly details like friction, youll need the same amount of work to get up to that speed, but how long it will take?Note that because work and time are scalar quantities (they have no direction power is a scalar as well.You occasionally run across symbol conflicts in physics, such as the W for watts and the.
