Mechanics is a branch of Physics that is concerned with the study of motion and forces on objects. The material here will concentrate on classical or everyday mechanics.
Classical Mechanics is divided into kinematics and dynamics. Kinematics is concerned with the motion of objects without consideration of the causes of motion. Dynamics concerns the relationship between the motion of bodies and its causes, namely the forces acting on the bodies and the properties of the bodies.
The knowledge of Mechanics is important for the development of the products we use. It is also an interesting and exciting subject of value in many walks of life. There is a great need for people who understand scientific principles and know how to think logically. Your knowledge and skills in these areas can help you excel in school, advance your career or improve your business.
The purpose of these free online lessons is to give you a start at improving your scientific knowledge of physics that will help you become a champion in the field.

Kinematics is concerned with the motion of objects without consideration of the causes of motion.
Dynamics concerns the relationship between the motion of bodies and forces causing that motion.
