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 is the name given to the center of gravity of earth moon system?
The barycenter is the point between the Earth and the Moon where they balance each other's gravitational pull.
What would be the affect of the Moon's and sun's gravitational pull on earth?
The Moon would continue to orbit the Sun, possibly in a different orbit. Assuming the Moon kept its (Earth) orbital velocity, this would cause it to move either slightly closer or slightly farther from the Sun. The Moon's relative velocity to the Earth is about 1 km/sec whereas the Earth-Moon system orbits the Sun at 30 km/sec. The sudden disappearance of the Earth would mean the continuation of the Moon's solar orbit, albeit possibly altered.
What is Venus' gravity in percentage?
Venus' gravity is about 91% of Earth's gravity, which means that objects on Venus weigh about 91% of what they would weigh on Earth. This is due to Venus having a similar mass to Earth but a slightly smaller radius.
Is Earth's gravity stronger than the gravity on Venus?
Yes. Venus has less mass and therefore has less gravity.
What keeps 99 percent of the total mass of the atmosphere within 32 km of Earth's surface?
Gravity keeps 99 percent of the total mass of the atmosphere within 32 km of Earth's surface. This force prevents the gases in the atmosphere from escaping into space and holds them close to the Earth's surface.
What terms can be defined as a root's downward growth as a response to gravity?
Geotropism or gravitropism are terms that describe a plant's root growth in response to gravity. Positive geotropism refers to roots growing downwards towards Earth, while negative geotropism refers to roots growing away from gravity, such as when they grow upward in a climbing plant.
Gravitropism (also known as geotropism) is a turning or growth movement by a plant or fungus in response to gravity. It is a general feature of all higher and many lower plants as well as other organisms. Wikipedia
Is a mass movement called a gravity occurs when sediment suddenly slips downhill in one large mass?
No, a mass movement occurs due to the force of gravity acting on sediment or rock material, causing it to move downhill. This movement can happen slowly over time or more rapidly as in landslides or rockslides. The mass movement is a result of the force of gravity on the material rather than being called a gravity.
How can heavy rains in the mountain cause flooding?
Heavy rains in the mountains can lead to flooding because the steep slopes cannot absorb the excess water quickly enough, causing it to flow downhill rapidly. This sudden rush of water can overwhelm rivers and streams, leading to overflow and flooding downstream areas. Additionally, the heavy rain can saturate the soil, increasing the risk of landslides and further exacerbating flooding.
What is a high specific gravity?
it is important because it helps determine what the mineral you are looking for is
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?
Yes. Without gravity, I would be floating in space right now.
Magnetism doesn't affect us directly, but it has many applications in industry.

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."
