Title: The Geometry of Forces for Equidistant Particle Paths
OM 214/2231
Abstract
Two geodesics in curved space are said to be initially parallel if there exists a mutually perpendicular line between them. Initially parallel lines on the sphere converge. Initially parallel lines in the hyperbolic plane diverge. So what happens if two particles (connected by a rigid rod of zero mass) travel along an inertial path in a curved space? While the center of mass travels along a geodesic the particles do not. A force is required along the rod to hold the particles in their respective paths. Put another way: What is the force of separation on the wheels of a car in hyperbolic space?
