Describe how distance affects gravitational potential energy - Middle School Physical Science

Question

Which of these objects would have the MOST gravitational pull if we were standing directly on the surface?

Answer

The answer is a planet more massive than the Earth, because it has the most mass.

Gravitational energy exists between all objects. We rarely talk about the gravitational energy that exists between objects here on Earth because the pull is so weak. We consider the effect of gravity more often when we talk about planets, stars, and galaxies because they are more massive and have much stronger forces of gravity at work.

The gravitational potential energy of an object depends on the mass of objects, and how far away they are from each other. More massive objects have more gravitational pull. (Remember that just because something is bigger, doesn’t mean it has more mass!) Objects that are closer together have more gravitational pull.

Weight is a measure of the effect of gravity on an object, and can change depending on where we are. Our mass never changes but we weigh less on the moon because there is less gravitational energy between us and the moon. The moon has less gravitational energy than Earth because it is less massive.

Assuming all of these objects have the same mass, which of these sets of objects would have a greater gravitational potential energy?

Answer

The answer is "the objects that are 10 meters apart" because they are closer together and thus have a greater gravitational energy between them.

Which of these two objects would have a greater gravitational pull?

Answer

The answer is "the 100 kg object" because it has a greater mass. Reminder that the size of the object does not affect the gravitational energy.

What could you do to these objects to DECREASE the gravitational energy between them?

Answer

The answer is "both of these" because increasing the distance and decreasing their mass would both decrease the gravitational pull.

Question

Does a plane have more gravitational energy when it is flying 100km above the Earth or when it is on the ground?

Answer

The answer is "when it's on the ground" because it's closer to the body that it's being pulled towards. Though this difference is hardly noticeable until we are high enough to leave the atmosphere.
