Information

Description

Interactive rectilinear motion simulation for exploring Uniform Rectilinear Motion (MRU) and Uniformly Accelerated Rectilinear Motion (MRUV) with one or two particles simultaneously, while observing position, velocity, and acceleration over time.

Physical model

The model is purely kinematic: position, velocity, and acceleration are related by the equations of MRU (constant velocity) and MRUV (constant acceleration), allowing the behavior of two particles with different initial parameters to be compared directly on the same timeline.
