Where does the roller coaster's kinetic energy come from?

It is converted potential energy

It was created by gravity

Hamsters ran in a wheel

Motors created the energy

I do know that it's not created by gravity

It should be  A) It is converted potential energy

Explanation:

Potential energy can be converted into kinetic energy, and kinetic energy can be converted into potential energy

Hope this helps u!!!

in 1972 the fluid—mosaic membrane model of membrane structure was proposed based on thermodynamic principals of organization of membrane lipids and proteins and available evidence of asymmetry and lateral mobility within the membrane matrix [s. j. singer and g. l. nicolson, science 175 (1972) 720–731].
