A Look at Rotational Motion

<p>In <em>A Look at Rotational Motion</em> fundamental scientific concepts in physics are explained through easily understood text and colorful illustrations and photographs. Young readers learn that any object that is moving in a straight line has linear motion. A bicycle moving in a straight line has linear motion but because bicycle wheels are round and move in a circle the wheels also use nonlinear or rotational motion. The word rotate means to turn around a center point. Rotational motion is a type of movement where an object turns around a center point. Rotational motion can be demonstrated by placing a dot on the side of a bike wheel turning the wheel and watching how the dot moves. Other examples of objects using rotational motion are illustrated: a spinning top a rolling ball windmill blades and airplane propellers.</p><p></p><p>A pronunciation guide of scientific terms is included. 24 pages.
