Can someone derive the formula to calculate the GPE of a mass which is away from the Earth by considering 0 potential at Earth's surface

GPE stands for gravitational potential energy, which is the potential energy that an object possesses due to its position in a gravitational field. It is important to consider 0 at Earth's surface because it allows us to calculate the change in GPE as an object moves from one point to another, and it also helps us understand the relationship between the height of an object and its potential energy.
The formula for calculating GPE is GPE = mgh, where m is the mass of the object, g is the acceleration due to gravity (9.8 m/s^2 on Earth), and h is the height of the object above Earth's surface. In this formula, h represents the change in height from the reference point, which is considered to be 0 at Earth's surface.
Yes, GPE can be negative if the reference point is taken to be above Earth's surface, such as in outer space. A negative GPE indicates that the object has less potential energy at that point compared to being at the reference point. This means that work would need to be done on the object to bring it back to the reference point.
The mass of an object does not directly affect its GPE. However, a heavier object will have a greater force of gravity acting on it, which will result in a larger change in GPE as it moves from one point to another. This is because the formula for GPE includes the mass of the object.
GPE is important in many real-life scenarios, such as calculating the potential energy of water in a hydroelectric dam, determining the energy needed for a roller coaster to complete its course, and understanding the energy required for a satellite to maintain its orbit around Earth. GPE is also used in studying the behavior of tides and ocean currents.
