Classical Mechanics

classical mechanics banner 3 Classical mechanics is a branch of physics that deals with the motion of bodies in accordance with the general principles by Isaac Newton's laws of mechanics. Classical mechanics describes the motion of objects larger than a molecule and smaller than a planet, close to room temperature and going at speeds significantly slower than the speed of light. Classical mechanics gives accurate results as long as it is limited to large objects and the speeds less than the speed of light.
