Newton's cradle: elastic collisions in a chain

Pull back 1 to 4 balls and watch the same number swing out; momentum and kinetic energy are conserved, and e < 1 damps it.

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: Newton cradle · elastic collision · momentum · energy
