Center of Mass Introduction

The video tutorial explains the concept of center of mass, using examples like a lacrosse ball and a hammer in projectile motion. It clarifies the difference between center of mass and center of gravity, especially in a constant gravitational field. Various objects, including a baseball bat and a Frisbee, are shown in projectile motion, highlighting their center of mass. The tutorial also covers systems of objects, such as ice cubes connected by a rod, and demonstrates how to find the center of mass in irregularly shaped objects using a hanging method.
