What is weight at the centre of the earth?
At the center of the Earth, the weight of an object is effectively zero due to the principle of gravitational equilibrium. As you move toward the center, the gravitational forces from the mass of the Earth around you pull in all directions, canceling each other out. Consequently, an object at the Earth's center experiences weightlessness.
Why at the center of the earth the gravitational force is zero?
if four horses with equal power are pulling one from opposite sides, it will not move. means net force would be zero. same is at center of earth. the mass of earth around center attracts equally to all sides( because geometrical center and center of mass are same). so net force is zero. On the other hand if you think of gravity as a force puling you into the centre of the earth then when you are at the center of the earth gravity must be zeero
Intensity of gravitational field of earth is maximum at?
The intensity of the gravitational field of Earth is maximum at its surface, where it is approximately 9.81 m/s². This value decreases as you move further away from the surface of the Earth.
Why does being farther from earth's center of mass cause you to weigh less?
Weight is the force exerted by gravity on an object, which depends on both the mass of the object and the gravitational pull it experiences. As you move farther from Earth's center of mass, the gravitational force decreases due to the inverse square law, which states that gravitational force diminishes with the square of the distance. Consequently, if you are at a higher altitude or further from Earth's center, you experience a weaker gravitational pull, resulting in a lower weight.
Most earth satellites follow an oval-shaped path rather than a circular path around the earththe PE increases when the satelite moves farther from the earth?
Most Earth satellites follow an elliptical path due to the gravitational pull of Earth and other factors affecting their orbit. The potential energy (PE) of a satellite increases as it moves farther from Earth because it gains height, resulting in a larger separation distance from Earth's center of mass, which increases its gravitational potential energy.
How does something gain gravitational potential?
An object gains gravitational potential energy when it is raised above the Earth's surface. The increase in distance from the center of the Earth leads to an increase in potential energy due to the gravitational force between the object and the Earth.
What factors do the gravitational potential energy stored between an object and earth depends on?
The gravitational potential energy between an object and the Earth depends on the mass of the object, the acceleration due to gravity, and the distance between the object and the Earth's center. This potential energy is stored in the object because of its position in the Earth's gravitational field.
When calculating gravitational potential energy you must use?
the distance between the object and the center of the Earth
What is the gravitational potential energy at the center of the earth?
Ideally, if the earth were a perfect sphere, the gravitational potential energy would be zero. In the center of a sphere all other points within the sphere have an equal and opposite counterpoint. They work to cancel each other out. However, the earth is not a perfect sphere so there would likely be a gravitational pull towards the area with the greatest mass.
What two ways can you change the gravatational potential engergy of an object?
You can change the gravitational potential energy of an object by altering its height or the strength of the gravitational field it is in. Increasing the height or the strength of the gravitational field will increase the gravitational potential energy, while decreasing either will decrease the gravitational potential energy.
Why gravitational potential at earth surface is zero?
The gravitational potential at Earth's surface is considered to be zero as it is the reference point from which gravitational potential energy is measured. Any object at Earth's surface has the potential to fall due to gravity, and this potential energy is typically defined as zero at Earth's surface for convenience in calculations.
What is the value of Earth's gravitational field at the center of the Earth?
In the cavity at the center of the Earth, your weight would be zero, because you would be pulled equally by gravity in all directions. - The gravitational field of Earth at its center is zero.
What direction does earth gravitational force act?
The Earth's gravitational force acts towards the center of the Earth.
What is potential energy called that depends on height?
Gravitational potential energy - it depends on the distance from the centre of gravity, so on Earth it depends on the height above the Earth's surface
Is there any place on the earth where there is not gravitational force?
The center of the Earth.
On earth the weight an height of an object give an object what type of potential energy?
The weight and height of an object on Earth give it gravitational potential energy. This type of potential energy is based on the object's position in a gravitational field relative to the surface of the Earth.
What combination of features will have the greatest gravitational potental energy?
An object will have the greatest gravitational potential energy when it has a large mass and is positioned far away from the center of the gravitational field, such as at a great height above the surface of the Earth. This combination of features results in a greater gravitational force acting on the object and allows for the potential energy to be maximized.
