System of Particles Translational Motion

The video tutorial explains the concept of the center of mass for a system of particles, using equations to describe its position in three-dimensional space. It introduces the idea of the ith particle and how to use position vectors and unit vectors. The tutorial further explores the velocity and linear momentum of the center of mass, applying Newton's laws to a system of particles. Finally, it compares the mass and volume of spheres with different radii, demonstrating the relationship between density and volume.
