Domino Chain Reaction

Theory

The ball’s potential energy $mgh$ turns into kinetic energy on the ramp. Each falling piece transfers energy to the next; the position of the centre of mass decides when a piece topples (when it leaves its base of support).

What to observe

• The wave of falls travels at an almost constant speed.

Try this

• Move the pieces closer or farther and see whether the chain continues.
• Draw obstacles with the pen using “solid stroke”.
