MaxineInfinity is chosen as a reference for measuring potential because it represents the maximum possible value in a scale. By setting infinity as a reference point, it allows for relative comparisons to show how other values or quantities measure up in relation to the greatest possible extent. This makes it easier to understand and analyze the potential of other values in comparison to infinity.

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.
Is potential energy on the surface of earth is always zero?
No, potential energy on the surface of Earth is not always zero. Potential energy depends on the reference point chosen, which affects the calculation of the potential energy. Typically, the reference point for potential energy on the surface of Earth is chosen to be at ground level, but it can be adjusted if needed.
Why earth is considered as zero potential?
Earth is considered to have zero electrical potential because it serves as a common reference point for measuring the electric potential of other objects or points in a system. Since Earth is so large and its charge is effectively neutralized by the presence of both positive and negative charges, it is commonly chosen as the reference point for zero potential in electrical circuits and calculations.
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.
An example of gravitational potential energy?
A book placed on a shelf has gravitational potential energy because it has the potential to fall due to gravity. This potential energy is stored in the book's position relative to the Earth's surface.
