the force that a celestial body exerts on any small mass close to its surface
The invisible force between objects that makes objects attract each other.
The most feeble of the four fundamental forces in the universe that affect all matter. The magnitude of gravitational attraction depends directly on mass and inversely on distance squared. For instance, the gravitational attraction between you and Earth is much greater than that between you and the Sun, even though the Sun is 333,000 times more massive than Earth. The distance separating you from the Sun weakens the mutual gravitational attraction, so as you stand on Earth's surface, Earth's gravitational pull on you is 1,650 times greater than the Sun's.
A force of attraction between all objects.
An attractive force between all objects. We feel the pull of gravity toward the center of our planet. We experience gravity as weight. An airplane must generate enough lift to counteract its own weight.
The force exerted on a body by the mass of the earth. It is equal to the "weight" of the body in pounds. The speed of a falling body under the action of gravity depends in practice on its density; that is, on the relation between its weight and the area it presents to air resistance. In a vacuum, the rate of descent of any body increases at the rate of 32ft per second every second.
seeming force of attraction felt between two or more objects with mass.
the force that every rc airplane is trying to beat. RC pilots are often caught out when gravity decides to have some fun and suddenly increases it's strength without warning. This common phenomenon is also known as pilot error or radio failure.
A basic force of nature that always attracts Helium atom - An atom possessing two protons and two neutrons in the nucleus, and two electrons.
the natural, invisible force between objects that attracts them to each other
A force of attraction that exists between objects. The greater the mass and diameter of an object, the greater its gravitational pull.
The attracting force that exists between two or more objects. Every object with mass has gravity, even though its effects can be minimal and undetectable.
The force imparted by the earth to a mass, which is at rest relative to the earth. A scientifically agreed value for gravity is 9.8 m/s2 or 980 cm/s2 and is called the acceleration of gravity.
attraction of the Earth upon any small mass near the Earth’s surface
The force of attraction between to masses pulling them towards the center of each other. The attractive force becomes less with distance. A mountain can attract and deflect a plumb bob from true vertica with the Earth's center.
force of attraction between all objects in the universe
A physical force attracting one object to another object.
Gravity is the attractive force of one mass on another mass. The weakest of the four forces of nature, gravity requires a very large amount of mass to be apparent. A 1 kilogram mass experiences a gravitational force of approximately 9.8 Newtons, pulled toward the 5,987,419,284,000,000,000,000,000 kilogram Earth. The pull of gravity decreases rapidly as the distance between the bodies increases.
The force on any body of matter at or near the earth's surface due to the attraction by the earth and its rotation.
A natural force exerted on a body toward the earth's surface or between two bodies. Gravity has a strong effect on how matter interacts. Gravitational attraction depends on the masses of the bodies involved and the distance between them. Centrifugal force caused by the earth's rotation on its axis tends to lessen the force of gravity.

An abbreviated term for gravitational force or gravitational force field, which is basically the universal ability of all material objects to attract each other.
One of the four forces of nature. The force depends on the masses of particles and their separations. Gravity has allowed galaxies, stars and planets to form.

The force of gravitation felt on Earth and other bodies in space. Gravity pulls objects toward the Earth. It also keeps the planets in orbit around the sun.
The attraction that all bodies have for one another.
A force attracting two bodies together. As you stand on the Earth gravity attracts, or pulls, you to the Earth's surface. In fact you also have an equal force on the Earth but because you are MUCH less massive than the Earth you don't notice it being pulled towards you
This is one of the four physical forces in the universe (the others being the electromagnetic force, and strong and weak nuclear forces); specifically it is the force of attraction that exists between all masses in the universe. It is proportional to the masses of the two bodies and inversely proportional to the square of the distance between them.
All objects feel a force do the mass of other objects, in proportion to the product of their masses, and inversely proportional to the distance between them. This force keeps the Earth in orbit around the Sun, and holds us to the surface of the Earth.
One of the four fundamental forces, gravity is the weakest force but it is always attractive and has an infinite range. Therefore its effects are cumulative and it is the dominant force for large scale structures in the universe such as solar systems, galaxies, and clusters. Einstein's theory of general relativity is a classical theory of gravitation. One of the major triumphs of superstring theory is that it is a consistent theory of quantum gravity (which contains general relativity in a low energy limit). Gravity is mediated by the spin 2 graviton.
mutual attraction affecting masses in universes, solar systems, and planets.
The natural force of attraction that pulls objects together - this is also what keeps our feet on the ground.
Viewed from a frame of reference fixed in the earth, force imparted by the earth to a mass which is at rest relative to the earth. Since the earth is rotating, the force observed as gravity is the resultant of the force of gravitation and the centrifugual force arising from this rotation and the use of an earthbound rotating frame of reference. It is directed normal to sea level and to its geopotential surfaces. The magnitude of the force of gravity at sea level decreases from the poles, where the centrifugal force is zero, to the equator, where the centrifugal force is a maximum but directed opposite to the force of gravitation. This difference is accentuated by the shape of the earth, which is nearly that of an oblate spheroid of revolution slightly depressed at the poles. Also, because of the asymmetric distribtion of the mass of the earth, the force of gravity is not directed precisely toward the earth's center. The magnitude of the force of gravity is usually called either gravity, acceleration of gravity, or apparent gravity. . acceleration of gravity. 3. By extension, the attraction of any heavenly body for any mass; as Martian gravity.

The force exerted by the Earth to hold us down. There is a equal but opposite force to gravity. called normal force. This normal force is perpendicular to the surface it is in contact with. The force of gravity exerted by the Earth on an object can be calculated by multiplying the mass of the object, by the acceleration due to gravity factor - 9.8 m/s2. Thus the formula becomes F = mg.

Is the process where any body of mass found in the universe attracts other bodies with a force proportional to the product of their masses and inversely proportional to the distance that separates them. First proposed by Sir Issac Newton in 1686.
or gravitational force An attractive force between matter. Gravity is one of the four fundamental forces of nature (the others are the electromagnetic, nuclear, and weak forces). For instance, gravity holds the planets together, keeps us on the surface of the Earth, and keeps the planets in orbit around the Sun.
the universal force of attraction that pulls all matter together.

The force of attraction between all objects. The more mass an object has, the larger the force of gravity it exerts. The Earth and beyond
Gravity is the force that attracts any two masses, bodies or particles towards each other. It is not restricted to the relationship between objects and the Earth – it exists between all things, everywhere in the universe. Sir Isaac Newton is credited with discovering gravity around the turn of the 18th Century. He realised that for an object to move, change speed or alter its direction, a force had to be applied to it. He called this force 'gravity'. The story of the apple falling from the tree has become a famous example of this effect. The force of gravity around an object in space is felt in all directions, but decreases rapidly with distance. We never feel the Sun's gravity on Earth because of the massive distance between the two bodies. However, itâ€(tm)s the Sun's gravity that keeps our planet in its orbit. Equally, weâ€(tm)re not directly aware of the moon's gravity, yet itâ€(tm)s powerful enough to influence the tides of the oceans on Earth.

One of the four fundamental forces in the universe that affect all matter. It is the weakest of these four forces, and it is an attractive force. The magnitude of gravitational attraction depends directly on the mass of the two objects being attracted and inversely on the square of the distance between them. For instance, the gravitational attraction between a person and the Earth is much greater than that between a person and the Sun. Even though the Sun is 330,000 times more massive than the Earth, it is about 100 million times farther away from it than a person is. This distance weakens the gravitational attraction between the person and the Sun, so that the Earth's gravitational pull on a person at Earth's surface is 1653 times greater than the Sun's.

Although we haven't traveled to all the planets nor to the sun, we know their mass. This is through the study of the law of gravity.
Over the last century, the mechanism of operation behind three of the four fundamental forces, strong nuclear, weak nuclear, and electromagnetic, has been explained using the concept of messenger particles. Attempts are currently underway to combine the concept of quantum mechanical messenger particles and the general relativity theory of gravitation into a unified whole. Hence, how the force of gravitation interacts with the other three fundamental forces is an open question.
