Can you stack four blocks on top of a table, so that they extend as far right as possible and still remain stable? This simulation lets you try - with full explanations!
Shows collision between two spheres. Set by user. Shown both in laboratory frame of reference and center of gravity frame of reference. Good to be able to explore collisions in both of these frames of reference.
Useful simulations (applets) on various Physics topics including mechanics, dynamics, waves, thermodynamics, electromagnetics, light, and optics with links to other sites.
