This book explains how forces such as electricity, magnetism, gravity, friction, air resistance and upthrust act and balance each other. The book explains how motion can be measured, and looks at examples of forces at work in everything from simple machines such as pulleys and levers to supersonic cars to objects in space such as planets and satellites.
