If the object's mass is 5 kg, then it's 5 kg. On Earth, on the moon, on Mars,
or floating weightless in a space ship coasting from one of them to another.
Weight depends on where you are, but mass doesn't.
An object with a mass of 5.0 kg has a mass of 5.0 kg on earth, on the moon, at the
bottom of Jupiter's atmosphere, thirty miles outside a black hole, or in a space ship
cruising from one to another of these places. You take your mass with you, and it
doesn't change.
Your weight changes. It depends on your mass, on the other masses that are nearby,
and on how far you are from them.
When your 5.0 kg object sits on the surface of the moon, it weighs about 1.8 pounds.
When it sits on the surface of the earth, it's still 5.0 kg of mass, but here it weighs
11.02 pounds. It weighs 4.2 pounds on Mars, 10 pounds on Venus, 29 pounds on
Jupiter, 10.5 ounces on Pluto, and nothing at all in the space ship coasting from
one place to the other.
But wherever it is, it's still 5.0 kg of mass
The mass of an object is unaffected by gravitational forces. Assuming we ignore relativistic effects (mass increase to infinite and so on) we can say that an object with a mass of 5kg will have that mass anywhere in the universe (within reason). On the other hand, an object that WEIGHS 5kg on earth will have a measured weight that varies considerably depending upon what gravitational fields are affecting it.
Because F=mg -> m=F/g On earth g=10 m/sec2 so m1=30/10=3 kg On the Moon g=0.16 m/sec2 so m2=30/0.16=180 kg m2
First of all, I will tell you the quick and easy way to find the answer. The equation is 9.8 multiplied by 5. You always use the number 9.8 because that is the measurement of Earth's gravity. You use the number 5 because that is the mass of the object you are measuring. That number changes depending on the object's mass. A 5kg backpack would weigh 49 Newtons on Earth. Good luck with science or whatever you needed this for!!
If I were to be in space which would be awsome I would be or you would be 3kg on the moon. If you were 30 kg you would be 5kg on the moon.
If it was weighed on the moon it would be 3kgs but obviously f it was weighed on earth it would be 5 kgs. if it was 5kg on the moon it would be about 8.2 kgs on earth

This object is very heavy weight.
Since mass is constant no matter what the gravity is, the mass would stay 5kg if you're on the moon, Earth, the Sun, Jupiter, Mars, Pluto, etc...Answers.com
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
The mass is 5kg
The rock's mass on earth will be 5kg (mass = force in newtons / 9.807)
a 10 kilogram dog + half of its mass (5kg) would be 15kg.
Mass is that property of an object which:Gives it inertia. More mass means it is harder to change an object's velocity.Makes it attract other objects, via the gravitational force. This is what gives the object its weight. (Weight also depends on the gravitational field.)The kg (kilogram) is the international unit for mass. It is APPROXIMATELY equal to the mass of one liter of water.
2 kgs
It is: 5kg-0.5kg = 4.5kg
Water's density is always less than that of mercury regardless of mass.
