What does gravity have to do with weight?
weight is equal to mass times by gravity ie W=mg this means that gravitational field strength, multiplied by the amount of matter that something is made up of (ie, 50kg, 10g, etc) is it's weight. so, you would weigh less on the moon, because the gravitational field strength is less, though your mass would be the same.

How can rockets escape from gravity?
Escape velocity is defined to be the minimum velocity an object must have in order to escape the gravitational field of the earth, that is, escape the earth without ever falling back.
From the surface of the Earth, escape velocity (ignoring air friction) is about 7 miles per second, (11.2 km/sec) or about 25,000 miles per hour. Given that initial speed, an object needs no additional force applied to completely escape Earth's gravity.

Does the width of a rubber band affect how far it will stretch?
Yes, the width of a rubber band can affect how far it will stretch. Thicker rubber bands tend to be stronger and can stretch further compared to thinner rubber bands. However, there are other factors to consider such as the material and elasticity of the rubber band.
What is the definition of gravity?
"The force of attraction by which terrestrial bodies tend to fall toward the center of the earth.How much you weigh on it
Gravity is the deformation of space-time. Imagine space-time as a mattress. Place a heavy ball on the mattress. What will happen? The mattress will be deformed by the ball. Now roll a little ball on the mattress. What will happen? The ball will approach the heavy ball because of the deformation and will begin to rotate around the heavy ball.
N.B.: It is important to know that gravity and time are the same thing. The more space-time is distorted, the more time passes quickly.
N.B.: A planet that is smaller than another planet but has the same mass will deform more space-time.
gravity is like a matress that the objects of the universe sit on holding them in place.
The force of attraction by which terrestrial bodies tend to fall toward the center of the earth.
(By the way, "defenition" is actually spelled definition.)
The term "gravity" comes from the Latin word "gravitas," meaning weight or heaviness. It was first used by Sir Isaac Newton in the 17th century to describe the force that pulls objects toward each other.
It's a place where gravitational force has been accurately measured, usually marked with a bronze plate with the results. Here's a link: http://www.holoscenes.com/cgi-bin/moin.cgi/gravity_station
Why is there less gravity at the top of a mountain?
== == All bodies in space warp space to one degree or another depending on their size and composition....their gravity is directly proportional to the center of their mass ...in other words the closer to its core the stronger the gravity ...conversly the further the weaker (a mountain)
What factors affect the amount of air resistance on an object?
The main aspects that affect the amount of air resistance against a particular object are the weight of the object and the speed that it is travelling at. The other important aspect is the shape of the surface area in the direction the object is falling.
There are 4 fundamental forces in nature: Gravity, electromagnetic, and the strong and weak nuclear forces. It is postulated that these 4 forces can converge into 1 super force, whose equation governs all. However, gravity is giving physicists the biggest trouble in discovering such a convergence. Gravity and electromagnetism share almost the exact same equation, except for a difference in a constant.
Also, there are other laws in nature that do not deal with forces, but rather concepts. These may include the 1st and 2nd law of thermodynamics, the law of conservation of energy, the law of conservation of momentum, and many, many more.
The most peculiar to me is the law of conservation of mass and energy. This states that the mass and energy in any closed system is always constant. Let the universe be this closed system, and in other words, mass and energy are never destroyed, only transformed!!! Think about the billions of stars, and the billions of planets, inside the billions of galaxies, that contains all of the tremendous amounts of energy in each star, and just before the big bang, this was one tiny, point object of near infinite mass and infinite energy! One point in space, smaller than a spec of dust, blew apart and created all of the things you see today in the universe, as well as provided all of the energy! Amazing.
What does measure the force of gravity acting on an object mean?
Measuring the force of gravity acting on an object involves quantifying the pull that Earth's gravity exerts on the object. This is typically done using a scale or a balance to determine the object's weight, which is a measure of the gravitational force acting on it. Weight is directly proportional to the force of gravity.
The more massive an object is, the more gravity it has. The farther you get from an object, the less you are effected by the gravity. Nothing effects gravity. Gravaty pulls you down. To stay a float go to space. Gravity does just pull you to earth, but I hear that it has something to do with magnetism as humans and animals all have microscopic magnetic substances that might have some connection with the magnetic forces of the earth and other planets. About the space thing, you don't have to knock on NASA's door to go to space, either, as there are space camps and place like that that allow you to go zero grav for a small fee. The strength of gravity is affected by the mass of the object in question and the distance from it.
Why is gravity's force on a mountain is greater then its force pulling on us?
A mountain has far more mass than a human being. Objects with greater mass have a naturally higher level of gravity themselves, and thus have a greater attraction to the earth itself, working with its gravity. Keep in mind that while you would calculate more force between the earth and the mountain, if you and Mt. Everest could be suspended above the earth in a vacuum and released, you would both fall to the earth at the same velocity. The greater mass of the mountain is off-set by a proportionally greater inertia. Don't get fooled as Aristotle did, and assume that the mountain would fall faster than you (in a vacuum).
What is the force that pulls objects toward each other?
Gravity.
It could also be electromagnetic force like in magnets having different poles.
It could also be strong and weak nuclear forces.
Measure of the force of attraction between objects due to gravity?
The measure of the force of attraction between objects due to gravity is called weight. Weight is determined by the mass of the objects and the gravitational force acting on them, commonly measured using units such as pounds or newtons.
It is unclear why gravity exists, but it is associated with matter and mass. The more massive an object, the greater the gravitational force it exerts. From the general theory or relativity, time is slowed by mass and the path of a particle in the vicinity of a mass is curved in an attempt to go in a straight line in curved space time. If this statment is correct then gravity was created in the big bang when quarks combined to form particles with mass. There is one worrying aspect to this simple picture, Light has no mass only energy, according to Einstien's E=MC2 mass and energy are related but then it is implied that gravity acts on energy. The energy of a particle is a function of its wavelength, its wavelength and spin being a function of time. I believe that ultimately gravity comes from the combined spin of all the particles that go to make up the mass in question. Unfortunately this is just metaphysics as it is not possible to test. Gravity is a characteristic of all mass, and it is not yet clear what the nature of gravity really is. It is possibe that it is related to the as yet undiscovered Higgs Boson. When we develop a "theory of everything", it will give us a picture of gravity that can be explained in Quantum terms, and this will be a huge step forward. The problem of gravity acting on light is actually addressed above. Light bending as a result of gravity can be seen not as a 'force' acting on massless photons, but as light passing through space that is itself warped. Light follows what is for it the straightest path through space.
The equatorial acceleration due to gravity on Saturn is 1.065g , just a little bit more than Earth's.
Edit: Yes, that's what most sources seem to say, but not all. There are some difficulties such as defining where the "surface" begins. Also some sources
mean "effective " or "apparent" gravity and that takes into account the
"centrifugal" effect of the planet's rotation.
In fact NASA give different values on different web pages.
This is particularly irritating for Saturn because it means things "weigh"
more, or less, than on Earth, depending on the definition.
Its surface gravity is similar to the Earth's. Some sources say it's a bit more, others say it's a bit less.
The pull of gravity on an objects mass called?
i am pretty sure it is weight.
Yup. Its definitely Weight. :D
How are gravity and velocity related?
Gravity and velocity are related in the sense that gravity is the force that pulls objects toward each other, causing them to accelerate. As an object moves faster (increases velocity), it may experience a larger gravitational force depending on its mass and the mass of the other object. Thus, velocity can affect the gravitational interaction between objects.
Gravity flow is fluid flowing due to the forces of gravity alone and not to an applied pressure head. In the Bernoulli equation, the pressure term is omitted, and the height and velocity terms are the only ones included.
What is the pull of gravity on an object called?
The pull of gravity on an object is called weight. It is the force that acts on an object due to gravity pulling it towards the center of the Earth.
Formula of gravitational force?
F = G m1 m2 / R2
G = the universal gravitational constant = 6.673 x 10-11 cubic meter per kilogram-second
F = the force between 2 masses
m1 = the mass of one of the masses
m2 = the mass of the other mass
R = the distance between the centers of mass of the two masses
== F=m*a Force = mass * speed a = F/m For the same Force F
the speed is big for small mass
the speed is small for big mass == The more mass something has, the more force is required to accelerate it to a given speed. The less mass something has, the less the force required to accelerate it to a given speed. Simple and easy. For a given amount of force, the less the mass it is applied to, the higher the speed that will result. The more the mass to which it is applied, the lower the speed that will result. It's just that simple.
What keeps an object in motion?
An object in motion will stay in motion unless acted upon by an external force, as described by Newton's first law of motion. In the absence of any external forces, an object will continue moving at a constant velocity in a straight line due to inertia.
Gravity is a force between two objects that is a function of the mass of each object and the square of the distance between them. It is one of the fundamental forces and combining it with quantum mechanics and the electromagnetic and intermolecular forces is one of the goals of modern day physics the end goal being a grand unified theory. It is not logical to ask for examples of gravity but perhaps if you ask again and reword your question to "What are some examples of events generated but the force of gravity on objects?" you might get some better answers to what I suspect you are asking.
