The object's mass doesn't change, no matter where it is or where it goes.
the center mass of an object is in the center of such objects. you can find it by spining the object. :)
The mass of an object doesn't depend on the gravitational force on the object.
No. The mass of an object does not change. However and object's weight, which is a function of mass and gravity, is less on the moon than on earth.
Mass is the measure of the amount of material in the object being directly related to the number and type of atoms present in the object. Mass does not change with the body's position, movement or alteration of its shape unless material is added or removed. The weight of the object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity. Since the weight is a force, density is mass/volume. If an object has a mass of 1kg on Earth is would have a mass of 1kg on the moon even though it would weigh 1/6th. as much. Mass is inertial property
momentum=mass*velocity 1*10=10Ns
The weight of any object is caused by the gravitational field of the nearest, large object. For a 1kg mass on the Earth its weight is about 10 Newtons. On the moon, the same 1kg mass would have a weight of about 2 Newtons.
Neither! They both have the same mass of 1 Kilogram.
Mass is a measure of how much matter something has. Weight is the effect of gravity pulling on that mass. So an object that weighs 1kg on Earth would weigh less on the Moon which has less gravity even though the mass of the object is constant. The relationship is: Force of gravity on an object in a certain place = (object's mass) x (acceleration of gravity in that place) .
Strictly, kg (kilogrammes) is a unit of weight rather than mass, which is measured in N (Newtons). This is important, because the MASS of an object does not change, whereas its WEIGHT does change according to the gravitational pull it is experiencing. On earth 1kg is about 10N. On the moon, say, something weighing 1kg would have a MASS of a little over 60N. If we change the word 'mass' in your question to 'weight', then the answer would be 'anything greater than 5kg'. If not, then 'anything greater than 50N subject to gravitational forces on the Earth's surface'. An object's INERTIA is the force that must be overcome in order to change its position (if stationary): so, it is clearly easier to move a 5kg object than it is to move any object that is heavier.
It is: 5kg-1kg = 4kg
1kg.
The weight of 1 kg is 1 kg on Earth. If the force is to be determined, it is 9.8 Newtons due to gravity.
None. The mass of an object won't change if you change the state of matter. When you burn it, the mass can change, since the atoms of the original object combine with oxygen, usually.
the Weight of an object is the force gravity exerts on it. So if you take a 1kg mass, on earth it pushes down 9.8n. but on say, the moon, you could take a 2kg mass, the amount of force it exerts downwards (the weight) would be less then the 1kg does on earth. So yes, but not if they are in the same place!
1 J= MgZ where Z is the elevation of the object; M=1Kg and g=9.8N/Kg --> 1=(1)(9.8)Z --> Z=0.1 m
