Classical Mechanics Concepts and Principles

The video introduces the concept of mechanics in classical physics, focusing on the study of matter and energy. It explains the difference between kinematics and dynamics, covering key variables like displacement, velocity, acceleration, and mass. The video also discusses the concepts of force, momentum, and work, and provides an overview of the symbols and units used in mechanics.
