Abstract
In this chapter we discuss the dynamics of rotational movements. The main object of study is the rotational dynamics of a solid body, but we will also consider the rotational movement of a particle or a system of particles. As we shall see in what follows, the dynamics of rotational motion has many analogies with the dynamics of the translational motion. At the same time, there are important differences, in part because of the cyclic nature of the angular variable. This property means that after increasing the value of the variable for a certain period (equal to \(2\pi\) in case of an angle), the body comes back to the same position. We will formulate the laws of rotational dynamics and find the corresponding conservation law.
