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?
That depends on what reference level you have chosen. If the (arbitrary) reference level you chose is Earth's surface, then anything on the Earth's surface has zero potential energy. If you choose some higher reference level, an object on Earth's surface has a negative potential energy. If you choose a lower reference level, an object on Earth's surface would have a positive potential energy.
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?
Any object that is above the chosen reference level has gravitational potential energy. If your chosen reference level is the ground level, a book on the table, or you yourself if you are standing rather than lying on the floor, have potential energy.

Does absolute potential energy both zero and negative at point of infinity?
There is really no such a thing as "absolute potential energy"; potential energy refers to the difference in energy between two points. For purposes of calculation, a convenient reference point is often chosen, and one such reference point is a point at an infinite distance.
What is the potential on the surface of the earth?
There is no absolute measure for potential energy. The calculation for potential energy depends on the chosen reference level. Quite often, the Earth's surface is chosen as the reference level - in this case, an object on the surface will have zero potential energy.

Why was water chosen as the standard of reference for measuring temperature and mass?
Because it is readily available nearly all over the world.
Example of gravitational potential energy?
Any object that is above the chosen reference level (often this is the ground level) will have positive potential energy. Any object below the chosen reference level will have negative potential energy.

Explain why reference points that are stationary are usually chosen to determine whether an object is in motion?
Stationary reference points are chosen to determine motion because they provide a consistent and fixed frame of reference. By using stationary reference points, it is easier to identify when an object is moving relative to its surroundings. This helps in accurately measuring the speed and direction of the object's motion.
What things store potential energy?
Several things, depending on the type of potential energy. Gravitational potential energy: Any object that is above the chosen reference level (often the ground level) has positive potential energy. Anything below the chosen reference level has negative potential energy. Elastic potential energy: For example, a compressed spring. Chemical energy: For example, hydrogen and oxygen separately have a higher energy level than when they combine into water.
Why does the driver have gravitational potential energy?
Any object that is above the chosen reference level has gravitational potential energy. Note that the choice of the reference level is arbitrary - in potential energy, it is the difference between two levels that matters; it doesn't make sense to talk about the potential energy in absolute terms. However, the ground level is often chosen as a reference level.
