Force and Motion looks at forces and motions and how physics, through simple and general concepts, affects the way people live and how the world around them works. No matter what form a movement takes, forces govern the motion. Some of these forces, such as the collision that sends a baseball flying away from a bat, are easy to observe; other forces, such as the one that gives a rocket its thrust, are more difficult to see. But all objects in motion obey laws, whether the object is a wheel or a baseball, a tsunami in the ocean or a person walking down the street. The same type of force also turns up in surprisingly distinct places—the force that keeps the space shuttle in its orbit is the same as that which gives a block of granite its weight.
