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 ofwater flowing downhill and spinning turbines is an example of gravitational potential energy transforming into kinetic energy.
alteration of metabolic rate,the matabolic activities increase so as to produce heat so as to maintain body temperature,that is why and individual consume a lot of meals during cold day.
