<strong>Work</strong> <strong>and</strong> <strong>Energy</strong><br />

Motion does not just mean the movement of an object from one<br />

place to another. When an object is compressed or stretched, the<br />

atoms within it are moved. Thus changes in the shape of an object<br />

constitute an exertion of force <strong>and</strong> thus result in work <strong>and</strong> energy<br />

transfers.
