Elastic and inelastic collisions in 1D and 2D

Two discs on a frictionless air table. Change masses, speeds, impact parameter and coefficient of restitution; watch momentum stay conserved while kinetic energy changes.

About this experiment

What you do in the lab

Change the controls and watch the physics behave in real time in 3D. Live readouts and graphs show the numbers behind it, and the Learn tab has the theory, procedure, observations and viva questions. Works on a phone or a laptop, in English and Hindi.

Topics: collisions · momentum · restitution · energy
