Pushes and Pulls

People do all sorts of pushing and pulling each day--from pulling their socks up in the morning to pushing a button to start their car. In this volume, the forces behind pushing and pulling are broken down for readers to grasp, as concepts of friction, changing direction, and changing shape are explained and detailed. Full-color photographs of each movement are featured to help readers visualize each concept, and achievable text broadens readers' understanding of pushes and pulls in their everyday lives.
