Dynamics is the study of the motion of objects (i.e. kinematics) and the forces responsible for that motion. It is a branch of classical mechanics, involving primarily Newton's laws of motion. As a field of study it is very important for analyzing systems consisting of single bodies or multiple bodies interacting with each other.
A dynamics analysis is what allows one to predict the motion of an object or objects, under the influence of different forces, such as gravity or a spring. It can be used to predict the motion of planets in the solar system or the time it takes for a car to brake to a full stop. Nothing that moves can be analyzed without using dynamics concepts. It is also important for understanding everyday things that are of interest to many of us, such as the physics of sports, and amusement parks.
