How is weight a force?
because it is experienced by pull of earth.weight of a body is equal to force by which earth pulls body towards its centre
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.
What is center of gravity of a body?
The center of gravity is the theoretical point where all the body weight is concentrated or the theoretical point about which the body weight is evenly distributed. If a body is of uniform density and has a symmetrical shape the center of gravity is in the geometric center. If the object is not symmetrical and does not have uniform density, it is more difficult to describe the location of its center of gravity.
What happens to the weight of an object when it moves farther away from the centre of the earth?
the weight of an object grows more
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.
Where on the earth would the weight of body be zero why?
on the centre of the earth.
Why does a body lose weight at the centre of the earth?
In the center of the Earth gravity is equal at every side causing you to be "weightless".
What is the definition of weight as it is used in science and technology?
Weight is the FORCE by which Earth PULL any body towards it centre of gravity.
Why is the weight of a body zero at the center of the earth?
At the centre of the Earth, or any body for that matter, the mass of the Earth is centralised at the centre, At the centre of the earth there is no weight attributable to the earth's mass. But there is weight (a force) attributable to the sun's mass, neatly balanced out by the speed of the earth in its circular orbit. So the weight is mv2/r instead of mg (m= a mass placed at the centre, v=velocity in orbit, r= distance to sun). If the earth slowed to a stop, it, and everything at its centre would accelerate towards the sun. If somehow you could nail the earth down so it didn't fall in, that weight would be measureable with a spring balance. Ignoring galactic and intergalactic forces. I guess that's sophistry really.

Where does a body have least weight equator or earth centre?
In the middle of the earth is where an object has the lightest weight. The weight is zero. The reason is that the mass of the object is pulled equally in all directions so all the forces cancel out.

GRAVITY?
The force that attracts a body towards the centre of the earth, or towards any other physical body having mass

What will be the mass of a body at the centre of the earth as compared to other places on the earth?
Mass is conserved which means that a body will have the same mass wherever it goes. But at the centre of a masive sphere the body has no gravity acting on it so its weight is zero. At an intermediated radius the force on it is obviously less than at the surface, and Isac Newton proved that a body at a given distance inside a sphere feels a gravitational force from a sub-sphere of radius equal the distance of the body from the centre. In other words the body feels no gravity from the shell outside its own radius.
