Abstract
Four examples are described where a force acts on an object to accelerate the object and where the displacement of the point of application of the force is zero. Work is done to accelerate the object but the total work done by the force is zero.
期刊介绍：
Physics Education seeks to serve the physics teaching community and we welcome contributions from teachers. We seek to support the teaching of physics to students aged 11 up to introductory undergraduate level. We aim to provide professional development and support for teachers of physics around the world by providing: a forum for practising teachers to make an active contribution to the physics teaching community; knowledge updates in physics, educational research and relevant wider curriculum developments; and strategies for teaching and classroom management that will engage and motivate students.
