Answer 2

When one hundred dominoes are placed upright in a row and the first domino is knocked over, one after another all the dominoes start to fall.

• The standing dominos contain potential energy into them.
• The Chain reaction is created when the first domino falls.
• The reason for the moving of the last domino is that the potential energy stored in it is changed into kinetic energy.
