Anyone can define a zero of potential energy, from which they are going to measure any other energy elsewhere. Like height, you take your zero to be the soles of your feet, or for a mountain, the sea level, or for a battery cell, one end of it. It may or not be possible to find a place in the universe where there is no lower gravitational potential. Note, usage is generally potential energy=potential x quantity (mass, charge etc).
What else can I help you with?
Is it possible for a person to have zero mechanical energy?
No, it is not possible for a person to have zero mechanical energy. Mechanical energy is the sum of an object's kinetic and potential energy, and as long as the person is in motion or has the potential to be in motion, they will have mechanical energy.
What is the potential energy at the ground?
The potential energy at ground level is typically zero, as the reference point for potential energy calculations is often set at ground level. This means that any object at ground level would have zero potential energy due to its height above the ground.
What does not have potential 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.

Why velocity of a mass attached to a spring is maximum at mean positions and zero at extreme positions?
This can easily be understood with conservation of energy. Assuming that no energy is lost, potential energy is continuously converted to kinetic energy, and vice versa. At the mean position, the potential energy is zero, therefore the kinetic energy (and hence the velocity) is at maximum.This can easily be understood with conservation of energy.

Is it possible for energy to have a negative value?
Yes, in certain contexts, energy can have a negative value. This can occur in physics when calculating potential energy or in quantum mechanics when considering energy levels below the zero-point energy.
Is it possible for a person to have zero mechanical energy?
No, it is not possible for a person to have zero mechanical energy. Mechanical energy is the sum of an object's kinetic and potential energy, and as long as the person is in motion or has the potential to be in motion, they will have mechanical energy.
Is it possible to have kinetic and potential energy at the same time?
yes it is, but you can only have kinetic energy of the object is in motion and potential energy if the object is any height above zero
What is the potential energy on ground?
Zero
What is the potential energy at the ground?
The potential energy at ground level is typically zero, as the reference point for potential energy calculations is often set at ground level. This means that any object at ground level would have zero potential energy due to its height above the ground.

Is it possible for the body to have more kinetic energy than potential energy?
Sure, any object at the reference level or ground level (whatever you define to be the ground level, for your calculations) will have zero potential energy; if it moves, it will have a positive kinetic energy. What's more, if the object is belowthe selected reference level, it will have negativepotential energy. In this case, even if it doesn't move, its kinetic energy (zero) will be greater than its potential energy (which is negative).

Can a system have negative potential energy, and if so, under what conditions is it possible?
Yes, a system can have negative potential energy. This occurs when the system's configuration is such that the potential energy is lower than a reference point, often taken as zero potential energy at a certain distance or position. This can happen in systems where attractive forces dominate over repulsive forces, leading to a negative potential energy.
Which of the following is the best definition of a zero energy state?
the lowest achievable energy state; the de-energization of electrical sources that includes discharging capacitive and inductive elements (absence of voltage and current) and blocking or totally releasing mechanical energy (kinetic or potential).
What is the Potential energy of a mass at the centre of the earth?
Zero
