it is conventional to define gravitational potential energy (GPE) of object A to be 0 when the object is free from the gravitational field of object B (i.e. at a infinite distance away)
As the objects get closer together, the GPE decreases, thus is less than 0. Therefore the GPE of any object normally has a negative value (however it all just depends on where you define to be the point at which the object has 0 GPE)

What is the gravitational potential at infinity?
With potential energy, what matters is the difference in potential energy, not the energy in absolute terms. To simplify calculations, the gravitational potential at infinity is arbitrarily set to zero. This gives objects that are nearer than infinity (to any object that attracts them gravitationally), a negative potential energy.With potential energy, what matters is the difference in potential energy, not the energy in absolute terms.

What is the law of gravitational potential energy?
Gravitational energy is the potential energy associated with gravitational force. If an object falls from one point to another point inside a gravitational field, the force of gravity will do positive work on the object, and the gravitational potential energy will decrease by the same amount.
What is the mathematical expression for gravitational potential energy?
Gravitational potential energy = (object's mass) x (acceleration of gravity) x (object's altitude)
What formula do you use to determine the Gravitational potential energy of an object?
Gravitational potential energy = (weight of the object) x (height) or Potential energy = (mass) x (acceleration of gravity) x (height)
What is gravitational potential energy related to?
The distance from the object providing a gravitational force.
Can the gravitational potential energy of an object be negative?
Yes, the gravitational potential energy of an object can be negative. This typically happens when the reference point for measuring potential energy is chosen to be at a higher level than the object's current position.
Energy at a height is called what?
Energy related to the height of an object is gravitational potential energy.Energy related to the height of an object is gravitational potential energy.Energy related to the height of an object is gravitational potential energy.Energy related to the height of an object is gravitational potential energy.
Can a objects mechanical energy be equal to its gravitational potential energy?
Yes, an object's mechanical energy can be equal to its gravitational potential energy. Mechanical energy is the sum of an object's kinetic and potential energy, and gravitational potential energy is a type of potential energy determined by an object's position in a gravitational field. When the object is at rest or its kinetic energy is zero, its mechanical energy will equal its gravitational potential energy.
Which does not affect the gravitational potential energy of an object?
The mass of the object does not affect the gravitational potential energy. Gravitational potential energy is determined by the object's height and the acceleration due to gravity.
How does an object get gravitational potential energy?
An object gains gravitational potential energy when it is lifted against the force of gravity. The energy is stored in the object's position relative to a reference point, such as the ground. The higher the object is lifted, the more gravitational potential energy it possesses.
What Does not affect the gravitational potential energy of an object?
The mass of the object does not affect its gravitational potential energy. Gravitational potential energy depends only on the height of the object above a reference point and the strength of the gravitational field.
Why gravitational potential is negative?
Gravitational potential is considered negative because work needs to be done to move an object from an infinite distance to a certain point in the gravitational field. As the object moves closer to a massive body, the potential energy decreases, resulting in a negative value to reflect the work done against the gravitational force.
What does not have energy?
Any object that is at "level zero" has zero potential energy. In the case of gravitational potential energy, this level is sometimes defined to be ground level, sometimes (in Astronomy) at an infinite distance (in this case, any object that is closer than infinity has a negative potential energy).Any object that is at "level zero" has zero potential energy.

When does an object have gravitational potential energy?
An object has gravitational potential energy when it is lifted to a certain height above the ground. This energy is stored in the object due to its position in a gravitational field. The amount of gravitational potential energy depends on the object's mass, the acceleration due to gravity, and the height it has been lifted to.
Can an objects mechanical energy be equal to its gravitational potential energy?
Yes. Mechanical energy is the sum of potential energy and kinetic energy; this includes gravitational potential energy.
How does gravitational potential energy work?
Gravitational potential energy is the energy stored in an object based on its position in a gravitational field. It is directly proportional to the object's height above a reference point. The higher the object is, the more potential energy it has. When the object falls, this potential energy is converted to kinetic energy.
What does not have potential energy?
Items or objects that are at rest or are not positioned in a way that requires them to do work do not have potential energy. These could include stationary objects like a book sitting on a table or a rock on the ground.
