In physics and engineering, dynamics (often referred to as dynamic motion) is the study of forces and their direct effects on the motion of objects. Unlike statics—which deals with systems at rest or moving at a constant velocity where all forces are balanced—dynamic motion focuses on systems where acceleration is non-zero.

The study of dynamic motion is broken down into two main branches:
Kinematics: This describes the geometric aspects of motion. It focuses on tracking position, displacement, velocity, and acceleration over time, completely ignoring the forces that caused the movement.
Kinetics: This bridges the gap between the movement and its root cause. It analyzes the active forces, torques, and masses that change how an object moves. The Core Principles Governing Dynamic Motion
Dynamic motion is heavily rooted in classical mechanics and Isaac Newton’s Laws of Motion:
