Question regarding gravitational potential

In summary, gravitational potential is the energy an object has due to its position in a gravitational field. It is different from gravitational potential energy in that it is a measure of potential energy per unit mass, rather than total energy. The equation for gravitational potential is V = -GM/r, and it changes inversely with distance. The unit of measurement for gravitational potential is joules per kilogram (J/kg).

do you know calculus? if yes, review the way you did dV/dr, if dr = (400000-39000) or (410000-400000), the answer will be closer, your second part is right...

the solution might expect you use the data table, so the number have some error...
 

FAQ: Question regarding gravitational potential

What is gravitational potential?

Gravitational potential is the amount of energy that an object has due to its position in a gravitational field. It is a measure of how much work would be required to move the object to a different position within the field.

How is gravitational potential different from gravitational potential energy?

Gravitational potential energy is the energy an object has due to its position in a gravitational field, while gravitational potential is the potential energy per unit mass. In other words, gravitational potential energy is dependent on the mass of the object, while gravitational potential is not.

What is the equation for gravitational potential?

The equation for gravitational potential is V = -GM/r, where V is the gravitational potential, G is the gravitational constant, M is the mass of the object creating the gravitational field, and r is the distance between the object and the point where the potential is being measured.

How does gravitational potential change with distance?

Gravitational potential is inversely proportional to distance. This means that as the distance between two objects increases, the gravitational potential decreases. This is because the force of gravity weakens as distance increases.

What is the unit of measurement for gravitational potential?

The unit of measurement for gravitational potential is joules per kilogram (J/kg). This unit represents the amount of energy per unit mass an object has due to its position in a gravitational field.
