Mr. phillips' car is parked on a steep hill with the brakes applied and the engine off. because of the car's position, it has gravitational potential energy. how could this gravitational potential energy be transformed into kinetic energy?

a. he could push it up the hill.

b. he could release the brakes.

c. he could start the engine.

d. all of these

He could release the brakes.

Explanation:

Gravitational potential energy is energy stored in an object due to its position, or height.

When Mr. Phillips' car is at the top of the hill, it has gravitational potential energy because it has the potential to roll down the hill. If the car started rolling down the hill, this potential energy would be transformed into kinetic energy. The easiest way to do this is to release the brakes.

Starting the engine or pushing the car up the hill would also be types of energy transformations, but they would not be transforming the gravitational potential energy into kinetic energy.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

unbalanced force
