Dynamics

Definition

Dynamics is the branch of physics that deals with the study of forces and their effects on the motion of objects. It encompasses the principles and laws that govern the behavior of systems under the influence of external forces, allowing for the analysis and prediction of how objects move and interact with their environment.
