College Physics 1 - Describing Motion

Explore the fundamental concepts of motion in physics, including position, displacement, time, speed, and velocity. Delve into modeling techniques using motion diagrams and vectors, laying the groundwork for understanding uniform motion and graphical representations in future discussions. Learn to differentiate between distance traveled and displacement, analyze vector addition, and apply these principles to real-world scenarios involving cars, runners, and even ants. This lecture serves as a crucial foundation for comprehending more complex physics concepts, despite the instructor's admitted fatigue during recording.
