Classroom PDF Notes
The Centre of Mass (COM) is a point where the entire mass of a system of particles is considered to be concentrated. It is the average position of all the parts of the system, weighted according to their masses. For example, if you have a system of particles, the centre of mass is the point where you can assume the entire mass is located for calculating motion.
A System of Particles refers to a collection of particles that may or may not interact with each other. These particles can be anything from atoms to large objects like planets. Understanding how these particles move and how their centre of mass behaves is essential for solving problems in physics.
