Rube-Goldberg Machine:
Watch this video then write a post on the OLP explaining how machines like this obey the law of conservation of energy:
Rube Goldberg machines obey the law of conservation of energy because there are chain reactions of energy taking place. Energy is transferred (usually kinetic) or sometimes transformed to one system/form to another. Energy may be lost (such as due to friction or sound) but in some places, some objects may even gain energy. The energy in the whole system is overall constant.
Perpetual-motion Machine:
Research examples of perpetual motion machines: Write an OLP post explaining: what are they? Why is it not possible to actually build one?
Give an example of one and outline the energy losses taking place.
A machine that can do work/energy indefinitely without any external energy source. It isn’t possible because it doesn’t obey the law of conservation of energy.
