39 work energy and power worksheet

Work is the exertion of a force over a distance. Energy is the capacity to perform work. Power is the rate of work performed per unit time. Notes: Students may find a basic physics text helpful in obtaining these definitions. "Work" is a difficult concept to precisely define, especially for students unfamiliar with basic physics. Solar power, that's obvious, but the energy in coal originally came from the Sun too. Prehistoric plants stored the Sun's energy in their leaves, and when they died and eventually formed coal seams, that energy was still there.

Work, Energy and Power In this section of the Transport unit, we will look at the energy changes that take place when a force acts upon an object. Energy can't be created or destroyed, it can only be changed from one type into another type. We call this rule conservation of energy.

energy work power worksheet answer key

The joule (J) is the metric unit of measurement for both work and energy. The measurement of work and energy with the same unit reinforces the idea that work and energy are related and can be converted into one another. 1.0 J = 1.0 N∙m, the units of force multiplied by distance. 1.0 N = 1.0 kg∙m/s 2, so 1.0 J = 1.0 kg∙m 2 /s 2.
