does the mass on the surface of the planet (in state of rest ) has inside it the same gravitational energy to a similar mass after a free falling above its surface for one entire second?

..to a similar mass after a free falling above its surface for one entire second?
Well, first you are taking the reference point to be the surface of the Earth and are correctly stating that it has zero potential energy relative to that position, THEN you are taking the reference point as being the center of the Earth and you are complaining that it has potential energy relative to THAT reference point, which of course it does. You need to make up your mind what your reference point is.nabil23 said:If the reference is the surface of the Earth, the mass will have zero gravitational energy ? so how the mass on the surface of the Earth cause pressure to the interior? it must have the energy to cause pressure.
I said that on the surface it has zero gravitational potential _energy_ relative to the surface. The gravitational _force_ is not zero.nabil23 said:If the reference is the surface of the Earth, the mass will have zero gravitational energy ? so how the mass on the surface of the Earth cause pressure to the interior? it must have the energy to cause pressure.
This is a commonly asked question among people who are curious about the laws of gravity. The answer is yes, the gravitational force is higher than it should be due to the concept of gravitational acceleration. This acceleration is caused by the mass of an object and the distance between two objects.
The gravitational force is measured using the universal gravitational constant, also known as G. This constant is used in the equation F = G(m1m2)/r^2, where m1 and m2 are the masses of the two objects and r is the distance between them.
Yes, the gravitational force varies on different planets due to their different masses and sizes. For example, the gravitational force on Earth is higher than on the Moon because Earth has a larger mass and size compared to the Moon.
No, the gravitational force cannot be manipulated as it is a fundamental force of nature. Although, the effects of gravity can be counteracted by other forces, such as the centrifugal force or the electromagnetic force.
The distance between two objects directly affects the gravitational force between them. As the distance between two objects increases, the gravitational force decreases. This is because the force of gravity follows an inverse square law, meaning that the force decreases by the inverse of the square of the distance between the objects.
