The flare.physics package provides classes for physical simulations involving particles, springs, and forces.

 IForce Interface representing a force within a physics simulation.
 DragForce Force simulating frictional drag forces (e.g., air resistance).
 GravityForce Force simulating a global gravitational pull on Particle instances.
 NBodyForce Force simulating an N-Body force of charged particles with pairwise interaction, such as gravity or electrical charge.
 Particle Represents a Particle in a physics simulation.
 Simulation A physical simulation involving particles, springs, and forces.
 Spring Represents a Spring in a physics simulation.
 SpringForce Force simulating a spring force between two particles.
