Rube Goldberg machines, follows the “law of conservation of energy as it uses a chain reaction to complete a simple task in different manner.
In this machine, various instant kinetic energy is transferred into potential energy and vice-versa, so the total energy remains conserved. Therefore, Rube Goldberg machines follows the law of conservation of energy.
In the machine when marble rolls down from the top it has kinetic energy, the marble hits and falls into a plastic cup, its kinetic energy is then transferred into potential energy that lifts the soda can. Then the potential energy is changed into kinetic energy.
When the marble comes in contact with the next marble, its kinetic energy is transferred to other marble.
