Summary
The term motion means a change in the position of a body with respect to time, as measured by a particular observer in a particular frame of reference. Until the end of the nineteenth century, Isaac Newton's laws of motion, which he posited as axioms or postulates in his famous Principia, were the basis of what has since become known as classical physics.
Filled with full-color and detailed figures, Forces and Motion, Third Edition explores these scientific topics and looks at how physics, through simple and general concepts, affects the way people live and how the world around them works. Each chapter focuses on a single aspect of force and motion, explaining these laws in accessible terms of the modern world.
