Unit 1: Mechanics

Most phenomena in the universe involve motion and energy. The importance of studying movement becomes evident when one looks at daily activities such as physical fitness, sports and driving cars. In this unit we will begin to understand why and how objects move. In physics, the topics of motion, force, work, energy, and power are called mechanics.
