Does weight act towards the centre of the earth?
Yes, at the center it becomes zero.
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.
How is weight a force?
Weight is a force that occurs due to the gravitational attraction between two objects, typically a mass and the Earth. It is the force exerted by the Earth's gravitational field on an object with mass, causing it to be pulled towards the center of the Earth. Weight is proportional to an object's mass, but can vary depending on the strength of the gravitational field.
How is the mass of a pencil different from its weight?
The mass of a pencil is the amount of matter it contains (its inertia), measured in grams or kilograms. Weight, on the other hand, is the force exerted on the pencil due to gravity, measured in newtons or pounds. Mass remains constant regardless of location, while weight can change depending on the gravitational pull.
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.

What is the name of the force that pulls objects up and down towards the centre of earth?
The force that pulls objects towards the center of the Earth is called gravity. It is responsible for keeping all objects on the surface of the Earth and plays a crucial role in determining their weight.
What is the force of gravity on an object's mass?
None, an objects mass (how much stuff there is as measured in kg and g or lb and oz if your old fashioned) is constant, no matter where it is in the universe.Gravity affects weight. The amount of gravity changes how much force (weight) is exerted on an object of a specific mass.E.g., on Earth, a 1kg object has a weight force of 10N towards the centre of the planet.On the Moon, the same 1kg object only has a 1.6N force exerted on it towards the centre, because the Moon has a weaker gravitational field than Earth.
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.
How you weight would change with the time if you were on a space ship traveling away from earth towards the moon?
It would be Gravitational pull
What would have an effect on an object's mass?
Nothing. An object's mass refers to how many atoms are present so unless you start chopping bits from it there will be no change in mass. An object's weight is its gravitational pull towards the Earth. Its weight could be affected by its position on the Earth because the Earth is not a perfect sphere. Objects have a higher mass at the poles than the equator as at the poles the objects are closer to the centre (center) of the Earth.
Do wrists get bigger with weight gain, and if so, how does this change occur?
Yes, wrists can get bigger with weight gain. This change occurs because excess weight can lead to an increase in fat and muscle mass throughout the body, including the wrists. The accumulation of fat and muscle tissue can cause the wrists to appear larger as they support the additional weight.
