In physics, power is the rate of doing work or of transferring heat, i.e. the amount of energy transferred or converted 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 (J/s), known as the watt (W) in honour of James Watt, the eighteenth-century developer of the condenser steam engine. Example problems: Work & Power •Two soccer players work out in the off season by sprinting up a 40? hill for a distance of 100 m before stopping, resting, and walking back down.

Terms in this set (10) The Work energy theorem equation. Where W is work being done, Kf is the final kinetic energy of The power is P = W/t = 19620J / 15s = 1308 J/s = 1308 W. P=f.v Energy . Energy is stored work. It has the same units as work, the Joule (J). There are many forms of energy: Spring energy: Work has been done on a spring to compress or stretch it; the spring has the ability to push or pull on another object and do work on it. The force required Energy can be converted between different forms. Let's start with a different example though, to understand the relation between power and energy. Distance and velocity. Distance is described in Work-Energy Fundamentals - PDF Version of Complete Toolkit. The PDF version of the complete toolkit contains all the resources with full descriptions in a printer-friendly format. Learning objectives and relevant standards are also included in the PDF Version of the complete toolkit. Work-Energy Fundamentals - Toolkit To Go Since work is a scalar quantity,therefore,power is also a scalar quantity.SI unit of power is watt (W).It is defined as:"The power of a body is one watt if it does work at the rate of 1 joule per second (1 J s-1)."Sometimes ,for example,in the electrical measurements,the unit of work is expressed as watt second.However,a commercial unit of Work-Energy Theorem. Work done by a force in displacing a body is equal to change in its kinetic energy. where, K i = initial kinetic energy. and K f = final kinetic energy. Regarding the work-energy theorem it is worth noting that (i) If W net is positive, then K f - K i = positive, i.e., K f > K i or kinetic energy will increase and vice-versa. Mr. Andersen defines the terms energy, work and power. He also uses a simple example to calculate both work and power. Intro Music Atribution Title: I4dsong_loop_main
