Indiana University Southeast Physics Applets: Brownian Motion Simulation

Detail Page «

Website Detail Page

written by Kyle Forinash

This web page contains a simulation of Brownian motion. One larger particle represents a macroscopically visible object (pollen grain) and smaller particles represent water molecules. Users may view speed vs. time or kinetic energy vs. time graphs as the particles collide randomly. Related context-rich questions elicit thinking about how average speed and average kinetic energy are related to object size. Are the objects in thermal equilibrium?

This page is part of a collection of Java applets with tutorial questions developed for students of undergraduate physics.
