Systems of Particles

Definition

Systems of particles refer to a collection of multiple objects or particles that are interacting with each other. These objects can be connected or separated, and their motion is influenced by external forces.

Center of Mass:

The center of mass is the average position of all the particles in a system. It behaves as if all the mass is concentrated at that point.

Momentum:

Momentum is the product of an object's mass and its velocity. In systems of particles, momentum is conserved unless acted upon by external forces.

Collisions: Collisions occur when two or more objects interact with each other for a short period of time. They can be elastic (kinetic energy is conserved) or inelastic (kinetic energy is not conserved).
