Why is it a good idea to discuss gravity and fluid flows when learning about electricity?

The flow of fluid molecules in fluid mechanics is synonymous to the flow of electrons in electricity.

Explanation:

The flow of fluid molecules in fluid mechanics is synonymous to the flow of electrons in electricity. Water, when it is falling by the force of gravity, can be used to turn turbines and generators that produce electricity.

A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy. Hydroelectric power plants are the most efficient means of producing electric energy.
