Ramps and Wedges


Book Description
How are a water slide and a ski jump alike? Why is pushing something along a ramp much easier than lifting it in the air? Why do skis zigzag down a hill? How can a simple wedge stop an airplane? This book answers these questions and shows you how different kinds of these two simple machines are all around you to make your work and play easier.
