Engineering Dynamics is the study of motion and the forces that cause it in mechanical systems. Unlike statics, which deals with bodies at rest, dynamics focuses on bodies in motion under the action of forces and moments. Key topics include kinematics, which describes motion without considering forces, and kinetics, which relates motion to forces using Newton’s laws. The subject covers the motion of particles and rigid bodies, work-energy principles, impulse-momentum methods, and vibration analysis. Engineering Dynamics is fundamental for designing machines, vehicles, and structures subjected to dynamic loads, ensuring performance, safety, and stability in real-world applications.
