Doing Work with Simple Machines
Simple machines help make difficult tasks easier for
humans and they're all around us. The books in this series explain what simple
machines are and explore the roles that simple machines have in our everyday
lives. Each book provides a number of examples of each type of simple machine
and where to find them. This series explores how forces and motion affect the
tasks we have to complete and how simple machines work to make doing these tasks
easier. Accessible language helps readers understand the complex subject
matter.
