Question

In comparing an electric circuit to a roller coaster, which part of the roller coaster would be equivalent to a battery?

Answer 1

I guess it would have to be the engine that drags the coaster to the top of the first hill.

Answer 2

so...its a question about energy transformation.
the rollarcoster is a example of energy transformation between kinetic energy and potential energy.while the battery is a transformation between chemical energy and electrical energy.that is some chemical reactions happen in the battery andtransform chemical energyv to electric energy:)
