Put Inclined Planes to the Test

What do staircases, dump truck beds, and ramps have in common? All of them are inclined planes! Inclined planes are simple machines. They help us to do jobs more easily. But don't take our word for it. Put inclined planes to the test with the fun experiments you'll find in this book. As part of the Searchlight Books™ collection, this series sheds light on a key science question—How Do Simple Machines Work? Hands-on experiments, interesting photos, and useful diagrams will help you find the answer!
