Particle Dynamics

Particle dynamics is a branch of classical mechanics that studies the behavior and interactions of discrete particles in systems such as gases, liquids, and solid granular materials. It encompasses various phenomena including motion under forces, collisions between particles, and collective behavior leading to macroscopic properties.

Key Concepts

  • Forces acting on particles (gravity, friction, electrical)
  • Kinetic energy and momentum exchange during particle interactions
  • Statistical mechanics for large ensembles of particles

Granular Materials

Granular materials exhibit unique behaviors due to interparticle forces and friction. The angle of repose is a critical concept describing the maximum slope at which a material can rest without slumping.
