Renewable Energy:
solar energy, wind energy, hydroelectric energy, biomass energy, hydrogen, and fuel cells, geothermal energy, and tidal energy.
Law of conservation
= Energy cannot be
created or destroyed it can only be
transformed from one form to another.
What is energy?
Energy is how things
change and move.
Transformation of energy
:red_flag: An Electric fan transforms electrical energy into kinetic energy.
:fire: A toaster transforms electrical energy to thermal energy to toast your bread.
:explode: The sun transforms Nuclear energy into heat and light energy.

Rube Goldberg Machine
It often uses simple machines such as levers, wedges, wheels and axles, pulleys, inclined planes and screws.
It is based on the equation where work = force applied x distance.
An example
:
Definition:
A machine designed to purposefully perform an uncomplicated task in an extremely complicated and indirect way while relying on chain reactions is called a Rube Goldberg (RG) machine.
Work is defined as force exerted over a distance.
W = F x D
A simple Machine is defined as any mechanical device that changes the direction or
magnitude of a force.
While Mechanical Advantage is the ratio of the output force and input force.
