Work out the potential of an object that is in between Earth and moon at a distance of 81.25 times closer to the moon than to the earth. Work out the force on the object at that point.Mandavi said:
Gravitational potential is the amount of work required to move an object from a reference point to a specific location in a gravitational field. It is a measure of the energy an object has due to its position in the field.
Gravitational potential is calculated using the equation V = -GM/r, where V is the potential energy, G is the gravitational constant, M is the mass of the object creating the field, and r is the distance from the object to the location where the potential is being measured.
A gravitational potential of zero means that the object is at the same potential energy level as the reference point. This typically occurs when the object is infinitely far away from the mass creating the gravitational field.
Gravitational field intensity is a measure of the strength of a gravitational field at a specific location. It is equal to the negative gradient of the gravitational potential. In other words, it is the rate of change of potential with respect to distance.
A zero gravitational potential means that there is no potential energy associated with an object at a specific location in a gravitational field. A non-zero gravitational potential means that there is a potential energy associated with an object at that location, and the magnitude of the potential energy depends on the distance from the object creating the field.
