m.g.h = (GMm)/r how can we prove that mgh is potential energy and both equal to that?
Gravitational potential energy is the energy possessed by an object due to its position in a gravitational field. It is the potential for an object to do work as a result of its position in a gravitational field.
The formula for calculating gravitational potential energy is GPE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height or distance from the ground.
Gravitational potential energy increases as the height or distance from the ground increases. This is because the higher an object is, the more potential it has to do work as a result of its position in the gravitational field.
Yes, gravitational potential energy can be negative. This occurs when the object is below the reference point, such as when it is below the ground level. In this case, the gravitational potential energy is considered to be negative.
Gravitational potential energy and kinetic energy are both forms of mechanical energy and are related through the law of conservation of energy. As an object falls, its potential energy decreases and its kinetic energy increases. At the bottom of its fall, all of its potential energy is converted into kinetic energy.
