In this section, include a summary of how your Rube Goldberg device design works from start to finish to complete a task. Your R
anyanavicka [17]

The energy conversions in the Rude Goldberg device design is as follows:

  • a quartz falls off from the roof: potential to kinetic
  • the quartz hits and lift a soda bottle: kinetic to potential
  • The soda bottle moves hits a battery: potential to kinetic
  • a battery which slides along into a torch that lights up: chemical to light

<h3>What is a Rube Goldberg device?</h3>

A Rube Goldberg device uses a set of reactions that work in succession with one event triggering the next event in the form of a chain reaction until the final event is completed.

The Rude Goldberg device design is as follows:

The design is of a unit that produces light when a quartz falls off from the roof. It then hits a plastic soda bottle and its velocity is converted into potential energy used to lift a soda bottle. The soda bottle then on rising hits a battery which slides along into a torch which then light up.

In conclusion, Rude Goldberg devices shows various forms of energy conversion.
