We live in a Universe of continual motion. Electrons swarming around atoms in matter, buses speeding along highways, planets orbiting the sun, the stars and galaxies rushing apart are all examples of matter in motion.
The branch of physics dealing with the motion of bodies as well as bodies at rest or in equilibrium is called mechanics. Since motion is such an important feature of the world around us, it is the logical subject to begin the study of physical phenomena. Therefore, we are offering this course entitled Elementary Mechanics as the first elective in physics. As the title suggests, in this course you will study elementary concepts and laws of mechanics, including the laws or conservation of linear momentum, angular momentum and energy.
