Mechanics

Mechanics is the study of things that move and the forces that make them move. Mechanics looks at how things work and the forces that cause them to change and move. This can include how objects move through space, how air and water move, how machines work, and even how animals and people move. Mechanics helps us understand how the world works and how to make things or machines move in the way we want them to.
