This book uses the But to be complete, we start with a discussion of rolling motion, which builds upon the concepts of the previous chapter. When you use a GPS device in a vehicle, it utilizes these physics equations to determine the travel time from one location to another. In the main part of this chapter, we explore the intricacies of angular momentum of rigid bodies such as a top, and also of point particles and systems of particles. Physics describes the relationship between the speed of an object, the distance over which it travels, and the time it takes to travel that distance. The concept of conservation of angular momentum is discussed later in this chapter. where s is the coefficient of static friction and N is the magnitude of the normal. When there is no motion between the objects, the magnitude of static friction f s is.

The small rotors at the tail of the aircraft provide a counter thrust against the body to prevent this from happening, and the helicopter stabilizes itself. The magnitude of the frictional force has two forms: one for static situations (static friction), the other for when there is motion (kinetic friction). The body of the helicopter tends to rotate in the opposite sense in order to conserve angular momentum. The lift blades spin about a vertical axis through the main body and carry angular momentum. The AP Physics 1 course is designed to be the equivalent of a first-semester, algebra-based, college-level physics course. The helicopter shown in the chapter-opening picture can be used to illustrate the concept of angular momentum. Any massive object that rotates about an axis carries angular momentum, including rotating flywheels, planets, stars, hurricanes, tornadoes, whirlpools, and so on. Angular momentum is the rotational counterpart of linear momentum. Studying physics will help you develop good thinking skills, problem solving skills, and give you the background needed to differentiate between science and.
