The strength of Earth's gravitational acceleration at ground level is approximately 9.81 m/s^2. This value is commonly denoted as "g" and represents the acceleration experienced by an object in free fall due to Earth's gravity.
the distance of the troposphere from the Earth is about 17km from the equator and 5-6km from the poles
Yes, altitude is a measure of height above Earth's surface, typically measured in feet or meters. It can be used to indicate how high an object is located in relation to sea level or ground level.
Yes. Weight is the gravitational force X the mass of an object. The further away from the center of the earth, the less the gravitational force. So you would weigh more at sea level than you would on top of Mt. Everest.
When the water table rises to ground level, it means that the level of water below the Earth's surface has reached the same level as the ground. This can lead to issues like flooding, marshy conditions, or water seepage into basements or foundations. It can also affect plant growth and the overall ecosystem of an area.
The highest point on Mount Everest when viewed from ground level is the summit, which reaches an elevation of 29,032 feet (8,848 meters) above sea level.

If an object is above ground level, it has positive gravitational potential energy. (This assumes you define ground level to be zero - actually, you can define any level to be zero.)
Gravitational potential energy = Mass x gravity x heightTherefore, an object at ground level is 0 meters above the ground, thus having no potential energy.PE = mghm = massg = gravitational accelerationh = height
Any object above ground level has gravitational potential energy. Actually, ground level is commonly chosen as the reference level, but any other level may be chosen as well. The choice is arbitrary.
Yes, gravitational potential energy can have a negative value when an object is located below a reference point, such as the ground level.
Water stored in a hydroelectric dam has gravitational potential energy due to its position above ground level. A rock held at the edge of a cliff has gravitational potential energy because of its height above the ground. A roller coaster at the top of a loop has gravitational potential energy because of its position above the track.

An object has the most gravitational potential energy at its highest point, such as when it is lifted off the ground. This is because the gravitational potential energy of an object is directly proportional to its height above a reference point, usually the ground level.
As we lift a body of mass m from ground level to a height h, then work performed will be mgh which is equal to the difference in gravitational potential energy at the ground level and at that height.
Yes. Any object that is above a reference level has positive potential energy; anything below that reference level has negative potential energy. For example, if the chosen reference level is the ground level, anything below the ground level has negative potential energy. Please note that the choice of reference level is arbitrary. What matters is the DIFFERENCE in potential energy between two positions - and that doesn't change, whether you choose (for example) the ground level, or some other level, as a reference level.
It isn't clear to me what you mean with "indicators" - an object has positive gravitational potential energy if it has mass, and if it is above ground level (or above any other reference level you choose to define as level zero).
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.
