The weight of a person is not constant at all places on the Earth. The weight becomes zero at the center of the earth or far away from the Earth.

What is the gravitational force between the Earth and your body called?
Your weight. Weight is the definition of the force between the earth and other objects. Thus you weight is the gravitational force acting on you from the earth.
The weight that registers when you step on a scale is the response of your body mass to the pull of what?
The scale measures the amount of gravitational pull on your body from the earth, or what is known as weight.
What is the force between the earth and a body on earth?
The gravitational constant on Earth is 10 Newtons per kg (well exactly about 9.81 Newtons)
If your mass is 63.5 kg on the Earth what is your mass on the Sun?
Mass is constant, but weight depends on gravity. Your mass is the same where ever you are in the universe but your weight depends on how much the pull of gravity is. To put it another way, mass depends on how many particles or atoms are in your body and that is the same regardless if you are on the sun or the earth, so your mass on both the sun and earth is 63.5 kg. On the other hand the sun is much more massive than the earth so the sun pulls on you more than the earth and you "feel" more weight or pull from gravity.
What is the theoretical velocity of a freely falling body?
Depends what you mean by "freely falling". If you consider a body falling toward the earth through a complete vacuum, there is practically no limit to its speed. The gravitational attraction will cause the body to accelerate, so the speed will keep increasing until it collides with the earth. If the body is falling though the atmosphere, however, we must take air resistance into account. Let the force (downward) due to gravity be F. Let the drag coefficient of the falling body be C. Let m be the mass of the body, and v be the speed of the body. Then we have the equation; m dv/dt = F - Cv The speed will be constant when dv/dt = 0, so then F-Cv=0. Solving for v we get v = F/C, which will be the terminal velocity of the falling body. Close to earth, F=mg. The drag coefficient C is much harder to determine. It will depend on the shape of the object, and will also depend on the speed. However, you can look up values for C that can give pretty good approximations if the body is a nice shape.
Weight of a freely falling body?
If the 'weight' of a body is the gravitational force between the body and the Earth, then as long as the body stays at about the same distance from the center of the Earth, its weight is constant, and has no connection with its motion.
What happens to the weight of the body when it falling freely under the action of gravity?
Nothing. If the 'weight' of a body is the gravitational force between the body and the Earth, then as long as the body stays at about the same distance from the center of the Earth, its weight is constant, and has no connection with its motion.
Is the mass of the body constant at all places in the Earth?
Yes, the mass doesn't change. The weight may change, depending on the local gravity. The apparent weight will change even more, because of the (ficticious) "centrifugal force".
What force is acting on the weight?
Weight is , actually, the force experienced by a body on the earth's surface due to earth's gravity. It is expressed as the same way as force Force = mass*acceleration where as weight = mass*acceleration due to gravity Since mass of a body is constant and gravity is almost constant(9.8 m/s2 ) except at the poles where it is (10 m/s2 ) , a body has the same weight, wherever it is on earth.
What is the mass of body anywhere in universe?
The mass of the object is the same as it was when you measured it on Earth, but its weight is different in other places.
A body falling freely from a hight towards the earth moves with uniform?
It moves with uniform acceleration,because it has a constant force acting on it (its weight).
How weight can change?
As the mass of a body or things is constant , the weight only depends on the the gravity 'g'. As the gravity increases with the decrease of the hight of the mass from the centre of the earth , the mass also increases with the decrease of hight from the centre of the earth.
Why does the body's weight get smaller in space?
Weight depends on mass. More specifically, weight = mass x gravity. --- A body's weight is really just the force drawing it toward the earth. For our purposes, we can use Newton's law of gravitation which states that this force is given by Gm1me/r2, where G is the gravitation constant, m1 is the mass of the body, me is the mass of the earth and r is the distance between the body and the earth. G, m1 and me do not change as a body moves into space; however, that distance r becomes larger which makes the force smaller, and that force is the body's weight.
What is the measure of the gravitational force on an object is?
Basically it is the object's "weight". The gravitational force on an object is its Mass X Gravitational Constant. The gravitational constant is the acceleration of a free falling body towards another body, and on Earth is equal to 9.81 meters/sec2 or 32.2 feet/sec2. Thus while the MASS of an object is a constant physical property, the WEIGHT of an object depends on the local gravity field pulling on that MASS.
What is the weight of the body at the center of the earth?
In theory, at the center of the Earth you would have no weight.
Where does a body have least weight in earth?
Center of earth.
Does the weight of the body remains constant everywhere in the universe?
no it does not remain contant.
