Does elevation affect gravity?

Essentially, gravity holds our world together. In addition, gravity is weaker at the equator because of centrifugal forces produced by the planet’s rotation. Gravity is also a bit weaker at higher altitudes, being farther from Earth’s center, such as the summit of Mount Everest.

What two factors affect magnetic electric and gravitational attraction?

Mass and distance are the two factors that affect the gravitational force between any two objects.

Does magnetic field cause gravity?

Gravity is not affected at all by Earth’s magnetic field, because gravity is the attractive force of the mass of two objects, which is unrelated to magnetism. However, the interaction between the magnetic field and these particles deflects them around the Earth.

What causes a magnetic gravitational and electric field?

Scientists think that the Earth’s magnetic field is produced by the movement of electrons in the Earth’s core. The outer core is liquid metal because there is less pressure. As earth rotates the liquid in the core flows and causes electric charges to move creating a magnetic field.

What are three things that affect gravity?

The magnitude of this force depends upon the mass of each object and the distance between the centers of the two objects. Mathematically, we say the force of gravity depends directly upon the masses of the objects and inversely upon the distance between the objects squared.

At what elevation does gravity decrease?

Near the surface of the Earth (sea level), gravity decreases with height such that linear extrapolation would give zero gravity at a height of one half of the Earth’s radius – (9.8 m. s−2 per 3,200 km.) and altitude h in metres.

Does earth’s magnetic field affect gravity?

Earth’s magnetic field ‘boosts gravity’. Hidden extra dimensions are causing measurements of the strength of gravity at different locations on Earth to be affected by the planet’s magnetic field, French researchers say.

How does magnetism and gravity affect objects at a distance?

Both magnetism and gravity can affect objects at a distance. Both get weaker as the objects get farther apart. This is why you are affected by the pull of gravity from the earth, but not from distance planets. It’s also why two magnets may move together if you set them near each other, but if you set them far apart nothing will happen.

How can we measure Earth’s gravity field?

The researchers utilized magnetic field measurements taken by the GFZ-satellite CHAMP and some extremely accurate measurements of Earth’s gravity field derived from the GRACE mission.

How does the Earth’s gravity change over time?

“The Earth’s gravity field changes from one month to the next mostly due to the mass of water moving around on the surface,” said Watkins. “Because water in all its forms has mass and weight, we can actually weigh the ocean moving around. We can weigh rainfall, and we can weigh changes in the polar ice caps.”
