Dynamics is the study of objects in motion and the forces that cause it — the natural follow-on from statics, and a reliable source of FE exam questions.
Each topic below has video walkthroughs and a quiz that regenerates its numbers every attempt.
Dynamics Topics
Pick a subtopic and start
Kinematics
Describing motion — position, velocity, acceleration, and the four kinematic equations.
Force & Acceleration
Newton’s second law, f = ma, and the difference between weight and mass.
Work, Energy & Power
Potential and kinetic energy, conservation of energy, and the work-energy principle.
Impulse & Momentum
Impulse-momentum relationships and collision problems.
Mass Moment of Inertia
Rotational inertia, standard formulas by shape, and the parallel axis theorem.
Why Dynamics Matters
Beyond the exam
Where It Gets Used
Vehicle design, robotics, machinery, and any structure subject to moving loads. Predicting how something moves under force is the whole job in a lot of engineering roles.
How the Material Is Organized
Each video covers one concept or problem type, so you can jump straight to what you’re stuck on rather than working through a full lecture.
Quick Review with Shorts
Our YouTube Shorts sharpen dynamics skills fast — one concept per clip, under a minute each.
A Note on Textbooks
A good dynamics textbook is worth having alongside these resources. Look for one with clear explanations of the fundamentals, worked examples, and practice exercises covering kinematics, kinetics, and energy methods.
