Gravity
One of the four fundamental interactions, gravity is responsible for the fact that any objects with mass attract one another. According to general relativity, it is a space time curvature, but according to quantum mechanics it is the result of exchanges of virtual gravitons.

What does gravity do to earth?
It does nothing. Actually there is gravity because of earth. The earth (or any mass) pulls down (ie attracts ) everything towards itself according to Newton's Universal Gravitational Law which states that the force between two masses is directly propotional to the product of their masses and inversely propotional to the square of the distance between them. This force has an average value of 9.81 N/kg on the earth. This force is commonly called the weight of an object.
What is value of gravitational acceleration?
The value of gravitational acceleration on Earth is approximately 9.81 m/s^2.
What would happen if you generated gravity in a electromagnetic field?
The earth has gravity and an outer EMF. So the forces coexist.
An electrical cable has a gravitational force but extremely small. When a current flows through the cable an electromagnetic field is also created (EMF). An EMF can conversely generate an electric current. The EMF pushes the electrons along the cable in one direction. Gravitational force exists between the atoms. The forces can thus vectorially added.
The gravitational force on the surface of Jupiter is approximately 2.5 times stronger than the gravitational force on the surface of Earth. This is because Jupiter is a much larger and more massive planet than Earth, resulting in a stronger gravitational pull.
What is the process called when gravity starts to pull tectonic plates into the asthenosphere?
The process is called subduction. Subduction occurs when one tectonic plate is forced underneath another plate and sinks into the asthenosphere due to gravity. This process is responsible for the formation of deep ocean trenches and volcanic arcs.
The transfer of soil and rock downslope due to gravity?
This process is called mass wasting or mass movement. It involves the movement of soil, rock, and debris down a slope under the influence of gravity. Factors such as steepness of the slope, type of material, and presence of water can affect the rate and type of mass wasting that occurs.
How many bees does it take to lift up a laptop?
According to the "Mythbuster's Bug Special", about 23,000 bees would be required to lift up a laptop.
How does gravity deposit materials?
Gravity deposits materials through processes such as erosion, sedimentation, and mass wasting. Erosion involves the wearing away and transportation of particles by gravity-driven forces like water, wind, or ice. Sedimentation occurs when these transported particles settle out of the transporting medium, often forming layers of sediment. Mass wasting involves the downslope movement of rock and soil due to the force of gravity.
What is the earths center of gravity?
The Earth's center of gravity is located at its geometric center, which is also the center of mass where the gravitational pull of the entire planet can be considered to act. This point is constantly changing due to the distribution of mass within the Earth and its interactions with other celestial bodies in space.
Gravity cannot be stored like other forms of energy because it is a force that exists due to the presence of mass. Gravity is a fundamental force of nature that acts over distance and does not have a physical form that can be stored or captured.
Does gravity stop you from jumping?
Gravity works equally on every particle in a "standard" object which is why all objects fall at the same rate. Yes, you can exert an upward force greater than 1G when jumping, but even during the jump, gravity is already working on decelerating your upward speed and pulling you back down.
Is the gravity of earth is because of it rotation?
No - the gravity of Earth is due to its mass.
No - the gravity of Earth is due to its mass.
No - the gravity of Earth is due to its mass.
No - the gravity of Earth is due to its mass.
Do gravity and magnets affect people?

Does earth's magnetic field cause gravity?
No, Earth's magnetic field and gravity are two separate phenomena. Earth's magnetic field is generated by its core while gravity is a fundamental force that exists between all objects with mass. Gravity is responsible for the attraction between objects, including the force that keeps us anchored to the Earth.
What is real law of gravitation of newton in his own words?
Newton's Law of Universal Gravitation was first published in 1687 as part of his book,
Philosophiæ Naturalis Principia Mathematica. The publication is free of copyright, and may be viewed online.
Newton did not originate the concept of gravity, but was the first to demonstrate that the motion of the celestial bodies could be explained if they were acting under an attractive force which was inversely proportional to the squares of the distances between them, and proportional to their masses. The gravitational constant was not determined until two centuries later. Newton did not promote the invisible force of gravity in his work, or attempt to explain it. The book solves the equation of motion for several types of orbits acting under several different forms of radial forces, and explains several astronomical observations with an inverse square form.
The actual statements are similar to this one, "if bodies move uniformly in concentric circular orbits whose periods vary as the 3/2 power of the radii, then the centripetal forces acting on these bodies vary as the inverse-square of the radii of the orbits."
What do you call the force of gravity that causes things to orbit?
-- Without gravity, there would be no orbits.
-- Gravity bends the motion of a planet into a curve. Without gravity, the planet
would continue in a straight line, and there would be no orbits.
-- Once you completely understand gravity, you can figure out everything there is
to know about orbits, because it all comes from the behavior of gravity.
Is gravity a force of erosion?
Gravity is an agent of erosion... I'm not quite sure if it is erosion. In the science textbook I have right in front of me it says and I quote, "Gravity, running water, waves, wind and glaciers are all causes, or agents, of erosion. Although it says it's an agent of erosion it doesn't say it is erosion. An agent is a "cause" of something.
Where on earth is the pull of gravity the least?
The pull of gravity depends on the mass of the two objects attracted to one another, and the distance between them. The greater the distance between the two objects, the weaker the pull of gravity. For that reason gravity is strongest at low elevations (closer to the center of mass of the earth) and weakest at high ones (farther from the center of mass), although the difference is essentially impossible to notice.
How do you manage the lack of gravity in space?
You don't need gravity to survive, at least not in the short term.
The lack of gravity is a problem in the long term, though: Muscle and bone gets weaker - the body finds that it doesn't actually need all this muscle and bone when there is no gravity to fight, so it gets rid of it.
NASA is doing research on how to avoid this, for longer trips in the future. See for example related link on "pillownauts".
A cave that has collapsed because of gravity?
Caldera - if the collapse is into a volcanoe's magma chamber.
If into a limestone cave its is a shake-hole or sink-hole. (I think that may be a US / UK respectively, name division for the same feature.)
What is the change in the way a plant grows in response to gravity?
Plants are negatively geotropic, and grow away from gravity. Since the earth is the center of gravity as far as plants are concerned (not to mention us humans!), this of course means that plants grow away from the earth. This is because plants seek out sunlight, or whichever light they are being exposed to. The photons (light energy) make contact with the plants surface and results in the creation of a hormone known as auxin which causes cell elongation. Since this happens on the side exposed to the light, a plant regardless of it's position, will begin to angle towards the light. So if for instance you placed a light shining downwards and a plant upside down, the plant would grow 'backwards' so to speak and away from the earth and the source of gravity.
What is gravity and how does it affect earth?
Gravity is a force that pulls objects with mass towards each other. On Earth, gravity is what keeps everything grounded and causes objects to fall towards the ground when dropped. It also determines the weight of objects on Earth because it is responsible for the force that keeps us and everything else on the planet in place.
Does earth's gravity pull on everything?
Yes, anything that get's within a close range of the earth will be pulled on by earth's gravity.
What is the shape of ice cube at zero gravity?
At zero gravity (or the microgravity environment of the International Space Station) the high surface tension of a water droplet would pull it into a sphere. If left undisturbed (no waves of motion to distort its basic shape) and allowed to freeze while not in contact with the any of the walls of its container, it would form a near-perfect ice sphere.
However, that same surface tension would, if it came into contact with one of the freezer's walls, cause it to stick: resulting in a part-curved, part-flattened lump that would need to be scraped or pried away.
What pull of the gravity on seawater causes?
The pull of gravity on sea water is from the moon. This causes tides. Like when you are at the beach low tides and high tides occur right? So, the moon pulls on the earth and the water follows the moon's gravitational pull. Hope this helped:)
