Any point can be used as reference point, since the absolute amount of potential energy doesn't have any meaning; only the relative amount (i.e., increase or decrease between two positions) has.
Quite often, one of the following standards is used:
1. For calculations near Earth's surface, the reference point is the floor. However, you can use any other reference point if it makes your calculations easier.
2. For astronomical calculations, the reference point is at an infinite distance. Thus, all potential energies have negative values.
What else can I help you with?
Can the GPE (gravitational potential energy) be negative?
Yes, gravitational potential energy can be negative when an object is below a reference point or at a lower elevation than the reference point.
What is the reference point for gravitational potential energy?
The reference point for gravitational potential energy is typically set to be at an infinite distance away from the gravitational field, where the potential energy is considered to be zero. This allows for the calculation of the change in potential energy as an object moves within the field.
What properties of an object determine its gravitational potential energy?
The two main properties that determine an object's gravitational potential energy are its mass and its height above a reference point, such as the ground. The gravitational potential energy of an object increases with its mass and how high it is raised above the reference point.
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.
Gravitational potential energy depends on which two things?
Gravitational potential energy depends on the height of an object above a reference point and the mass of the object.

Gravitational potential energy depends on which two things?
Gravitational potential energy depends on the height of an object above a reference point and the mass of the object.
Can the gravitational potential energy of a system be negative?
Yes, gravitational potential energy can be negative. This can occur when the reference point for measuring potential energy is set at a lower height than the system. This means that the system has less potential energy relative to the reference point, resulting in a negative value.
What are the two factors Gravitational potential energy depends on?
Gravitational potential energy depends on an object's mass and its height above a reference point, such as the ground. The greater the mass and height of an object, the higher its gravitational potential energy.
How the gravitational potential is related to potential energy?
Gravitational potential is a measure of the gravitational potential energy per unit mass at a point in a field. The gravitational potential energy of an object at a point is equal to the product of the object's mass, acceleration due to gravity, and the height of the object from a chosen reference point. As an object moves in a gravitational field, its potential energy changes due to its position relative to the reference point.
What is the reference point for gravititional potentiel energy?
The reference point for gravitational potential energy is typically chosen to be at infinity, where the gravitational potential energy is defined to be zero. This allows for easy comparison of potential energies between different points in a gravitational field.
Where is its gravitational potential energy a maximum?
An object's gravitational potential energy is at its maximum when it is at its highest point in the system, such as at the peak of a hill or when it is the farthest distance away from the source of the gravitational field. This is because the potential energy is directly proportional to the height and distance from the reference point.
Is it possible for gravitational potential energy to have a negative value?
Yes, gravitational potential energy can have a negative value when an object is located below a reference point, such as the ground level.
What actions will increase the gravitational potential energy of an object?
Raising the object to a higher position will increase its gravitational potential energy. The gravitational potential energy of an object depends on its mass, the acceleration due to gravity, and the height from a reference point.
