What is the force of gravity on Earth and how does it vary?

  • Thread starter Boice_head

In summary, gravity on Earth is the force that pulls objects towards the center of the planet and is caused by the mass of objects. The value of gravity on Earth is approximately 9.8 meters per second squared (m/s²) and is affected by altitude, mass, and distance between objects. The Earth's shape does not significantly affect gravity, but its rotation causes a slight bulge at the equator and a slightly stronger gravitational pull at the poles.

As phrased your question cannot be answered. Please be more specific, just what do you mean?

What do you mean by "gravity"? The force of gravity is your weight (and varies from person to person, object to object). The "acceleration due to gravity" also varies slightly from place to place on the surface of the Earth but "9.81 m/s2" is a good approximation.
 

What is gravity on Earth?

Gravity on Earth is the force that pulls objects towards the center of the planet. It is also known as the gravitational pull of the Earth.

How does gravity work on Earth?

Gravity is a natural phenomenon that occurs due to the mass of objects. The larger the mass of an object, the stronger its gravitational pull. The Earth's mass is so large that it creates a strong gravitational force that keeps objects on the surface from floating away into space.

What is the value of gravity on Earth?

The value of gravity on Earth is approximately 9.8 meters per second squared (m/s²). This means that for every second an object falls, its speed increases by 9.8 meters per second.

How does the Earth's shape affect gravity?

The Earth's shape does not affect gravity significantly. Gravity is determined by the mass of an object, not its shape. However, the Earth's rotation does affect gravity slightly, causing the planet to bulge slightly at the equator and creating a slightly stronger gravitational pull at the poles.

What factors can affect the strength of gravity on Earth?

The strength of gravity on Earth can be affected by altitude, as gravity is slightly weaker at higher altitudes. It can also be affected by the mass of objects, as objects with larger masses will have a stronger gravitational pull. Additionally, the distance between two objects can also affect the strength of gravity, with a greater distance resulting in a weaker gravitational force.
