Simple Harmonic Motion
Mechanics is the study of the way matter and forces interact with each other. Here we are concerned with rigid macroscopic bodies. These are bodies that you can easily see, do not bend, and are in the solid state.
Mechanics has several fields. Among them are statics, dynamics, and kinematics.
Statics concerns itself with forces when no change in momentum occurs.
Dynamics is concerned with forces and matter when a change in momentum does occur.
Kinematics is a study of motion without regard to the forces present. It is simply a mathematical way to describe motion.
