Yes. Potential energy can't be specified in absolute terms; you have to arbitrarily define a reference point. For the case of gravitation, any object below the reference point would have negative potential energy. What matters is not the number assigned to the potential energy, but the difference - this difference would be the same, even if you change your reference level.

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.
Can an object have a negative potential energy?
No, potential energy is always measured as a positive value. It represents the stored energy an object has due to its position or configuration in a system. Negative values are not typically used to represent potential energy.
Is it possible to add energy to a system without increasing the temperature of that system?
Yes, it is possible to add energy to a system without increasing its temperature by converting the added energy into a different form, such as potential energy or kinetic energy. The internal energy of a system can change without a temperature increase if the energy is used for processes like phase changes or chemical reactions.
What kinds of energy does the internal energy of a system include?
The internal energy of a system includes kinetic energy (from the movement of particles), potential energy (from intermolecular forces), and thermal energy (from the temperature of the system).
Sum of kinetic energy and potential energy?
The sum of kinetic energy and potential energy in a system is the total mechanical energy of the system. This concept is described by the conservation of mechanical energy, which states that in the absence of external forces, the total mechanical energy of a system remains constant. The sum of kinetic and potential energy can be formulated as: Total mechanical energy = Kinetic energy + Potential energy.
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.
Is potential energy in k-shell is negative then why?
bcoz the energy of bound system is always negative
Can an object have a negative potential energy?
No, potential energy is always measured as a positive value. It represents the stored energy an object has due to its position or configuration in a system. Negative values are not typically used to represent potential energy.
Is it possible for exergy to be negative?
No, exergy is a measure of a system's potential to do work and cannot be negative. If the exergy value calculated for a system results in a negative number, it is likely due to errors in the calculations or assumptions made.
Is it possible to add energy to a system without increasing the temperature of that system?
Yes, it is possible to add energy to a system without increasing its temperature by converting the added energy into a different form, such as potential energy or kinetic energy. The internal energy of a system can change without a temperature increase if the energy is used for processes like phase changes or chemical reactions.
Why total electronic energy is negative?
In computational chemistry, the total electronic energy is often negative because it is measured relative to the energy of the separated atoms at an infinite distance, which is defined as zero. As electrons in a molecule experience attraction to the nuclei and repulsion from other electrons, their interactions result in a system energy that is lower than the reference point, hence negative total electronic energy.
What kinds of energy does the internal energy of a system include?
The internal energy of a system includes kinetic energy (from the movement of particles), potential energy (from intermolecular forces), and thermal energy (from the temperature of the system).
Sum of kinetic energy and potential energy?
The sum of kinetic energy and potential energy in a system is the total mechanical energy of the system. This concept is described by the conservation of mechanical energy, which states that in the absence of external forces, the total mechanical energy of a system remains constant. The sum of kinetic and potential energy can be formulated as: Total mechanical energy = Kinetic energy + Potential energy.
What energy is the sum of potential energy and kinetic energy in a system of objects?
The sum of the potential and kinetic energy of large-scale objects in a system is the Hamiltonian.
What happens to the potential energy of a system if the objects in the system are allowed to move freely?
If the objects in a system are allowed to move freely, the potential energy of the system will decrease as it is converted into kinetic energy of the objects in motion. As the objects move, potential energy is gradually transformed into the energy of their motion.
A energy is?
Energy is the potential to do some work. If there is work done on a system, this work done is stored as potential energy of the system. If the system in motion, it should have kinetic energy. Hence total energy of the system PE+KE
Potential energy plus kinetic energy equal what?
The sum of potential energy and kinetic energy is equal to the total mechanical energy of a system. Mechanical energy = Potential energy + Kinetic energy.
