You and your lab partners will work together, but you each must submit an individual lab report, with a discussion of the lab. Taken together, the topics reinforce the general idea that the behavior of many systems in the world can be described precisely with simple mathematics. Fundamental laws of motion, force and energy, particle collisions, rotational mechanics, gravitation, thermodynamics, and kinetic theory. Reflection, refraction, interference and diffraction. Classical mechanics describes the motion of macroscopic objects, from projectiles to parts of machinery, and astronomical objects, such as spacecraft, planets, stars and galaxies if the present state of an object is known it is possible to predict by the laws of classical mechanics how it will move in the future determinism and how it has moved in the past reversibility.
