# PHYS52 - Introduction to Force, Momentum, Work, and Energy

This is the third in a series of courses on basic physics. In the previous two courses the concept of a vector quantity was introduced, and then the vector quantities of position, velocity. and acceleration. These are the quantities that describe how something moves, the science of kinematics. In this course we begin to explore why things move, that is the science of dynamics. The concepts of momentum, force, work, and energy are an important part of the study of dynamics.
