Doing Work

Any time we use force to move something, we are doing work. Pushing, pulling, lifting, and twisting are all examples of work. This unit helps students explore the concepts of work and force. Students will learn that the amount of work required to perform a task depends on the amount of force needed to move it, as well as the distance an object will be moved. We are able to move things by only using our bodies, but using machines makes work easier and faster. Machines may be simple or complex. Each machine is well suited to help us perform certain tasks.
