Kinematics focuses on describing motion without considering the forces that cause it, while Dynamics examines the reasons behind that motion, including the effects of forces and mass. Kinematics deals with observable variables such as time, velocity, and displacement, providing empirical results of motion. In contrast, Dynamics explains the underlying principles and circumstances that lead to motion, answering the "why" behind observed phenomena. The discussion emphasizes that Kinematics is about observation, whereas Dynamics involves explanation and prediction. Understanding these distinctions is crucial for studying mechanics effectively.
