In potential energy, the important thing is the increase or decrease in energy; any absolute energy level is arbitrary. So, it all depends on what level is arbitrarily defined as zero. For example, if you define the floor level as zero, then anything above that will be positive, anything below that will be negative.

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.
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.
Why is the gravitational potential energy of two objects negative?
The gravitational potential energy of two objects is negative because it is defined as the work done by gravity when the objects move closer together, which results in a decrease in potential energy.
Is gravitational potential energy negative?
Yes, gravitational potential energy is considered negative because it is defined as the work done by gravity when an object moves from a higher position to a lower position.
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.
