Where is the greatest weight of the matter?
Note: The weight of an object is the least when it is placed in the center of the earth because the object in the center tries to pull from all sides of gravity & the weight of the largest object on the earth at the poles
Why weight in a vacuum rather than weight in air?
The apparent weight of a body is less in air than in a vacuum
But in a vacuum there is no resupination, and consequently in the emaciation of the body there is no diminution
And this is why a body weighs more in a vacuum than in air
When we weigh an object in the air, it puts down the air in that space, which provides the least upward force, the less it weighs
Why do objects of greater mass have more weight?
The mass is the measure of the thing (what has been done)
The greater the mass of the object, the greater the force of its gravity
The stronger the pull of gravity on an object, the more weight it has
In physics, weight is measured in newtons (N), a common unit for measuring force
Why is the greatest weight at the pole or at the equator?
You do so because the centrifugal force is at its greatest from the equator due to the rotation of the Earth, and it disappears at the poles
If you weigh 100 pounds on the spring scale at the North Pole, you will weigh 9965 pounds, or 55 ounces less, at the equator
The cow is the medium in which the weights are greatest
What is the weight of an object in a vacuum?
Therefore, all objects, regardless of size or shape or weight, fall freely with the same acceleration
What is the difference between weighing in air and weighing in a vacuum?
When a body is weighed on a spring balance, it will weigh more in a vacuum
When a body is lifted, the force of the air in the weighted air will reduce its weight
But in a vacuum there would be no such force, so the weight of the body is even more so, although it is insensible
Or do they fall more quickly in a vacuum?
In a vacuum (say, the moon) everything falls with the same speed, even if one is heavier than the others
What is the difference between the mass of an object and its weight?
The force with which the earth pulls objects towards the center is called weight…The difference between mass and weight
Weight = mass acceleration due to gravity
The SI unit of mass is the Kilogram (Kg)
It is a scalar quantity
It is a vector quantity
Since there is no easy practical way to measure mass, in everyday life we use the kilogram as a unit of weight assuming a fairly constant gravitational field around the earth
