Select the correct answer. Which description is an example of gravitational potential energy transforming into kinetic energy? A.)water flowing downhill and spinning turbines B.)upward currents of wind spinning blades of a windmill.
C.) plants performing photosynthesis D.) loudspeakers producing sound from electrical signals.

Option (A) is the correct answer.

Explanation:

In a gravitational field, energy possessed by an object is known as gravitational potential energy.

Whereas kinetic energy is the energy possessed by an object due to its motion is known as kinetic energy.

Therefore, out of the given options description of water flowing downhill and spinning turbines is an example of gravitational potential energy transforming into kinetic energy.
