On earth, 100 kg of mass weighs 980 newtons (220.46 pounds).
45 kg. The same. Your mass doesn't change on which planet you're on, but your weight does.
A mass of 100 pounds, weighs approx 444.5 Newtons. A kilogram is not a measure of weight, a Newton is.
Multiply the mass fraction by 100.
Nothing. 100 kilograms is a measure of mass, not weight.
The weight of an object is given as the formula W=mg where W is the weight, m is the mass and g is the gravitational acceleration (or the gravity of planet). On earth, g is generalized as 10 N kg-1(about 9.8 N kg-1 to be more exact). On the moon, it is about 10/6 N kg-1. So, the weight of a 10kg mass on earth would be 100 N (N is Newton, the SI unit for weight) while the mass would be 16.7 N on the moon.
The mass always stays the same, but because gravity is 38% of Earth, weight is only 38 pounds for every 100 pounds on earth.

The difference between a person's weight on the earth and on the moon has to due with the difference between mass and weight. Mass is a measure of the amount of matter and weight is the pull of gravity on that mass. Gravity on the moon is about 83% that on earth, so if you weigh 100 lbs on earth, you will weigh approximately 17 lbs on the moon.
You convert mass to weight by multiplying by the local acceleration due to gravity ...f = ma... where f is the force in newtons, mass is the mass in kilograms and a is the acceleration in meters per second squared. For the Earth, a is 9.81, so a mass of 100 kg has a weight of 981 newtons.It is "common" though erroneous to say that the "weight" of the 100 kg object is 100 kg. It is precisely correct to say the weight is 981 newtons, on the Earth, but we generally accept the implicit conversion for G=9.81 in the statement that the weight is 100 kg, just not on a physics test.
45 kg. The same. Your mass doesn't change on which planet you're on, but your weight does.
The mass of an object is unvarying. It's weight varies according to the gravitational force on the object. Weight = mass x gravity For a mass of 100 gms, which is 0.1 kg then its weight at the Earth's surface would be 0.1 x 9.78 Kg = 0.978 Newtons Its weight on the Moon would be a lot less and its weight in outer space would be virtually nil.
Your mass stays the same but your weight is different because it is the force that the planet's mass attracts your mass with. So if you are on a small planet your weight is less. A body with 100 pounds mass has a weight of 100 pounds on the Earth but only 17 pounds on the Moon, and zero pounds in space.
1,000 kg of mass weighs 9800 newtons on Earth, 1,620 newtons on the moon, and other, different weights in other, different places.
About 1/6 of what you weigh on Earth. For example, if you have a mass of 60 kg, on Earth you weight about 600 N, while on the Moon you would weight about 100 N.
The mass doesn't nessessarily change when weight does. The gravity may have changed. Mass and weight need some clarification. The mass of an object is measured in kilograms. That always remains constant. The weight of an object is measured in Newtons and is worked out by the product of the mass and the gravitational field strength, which on earth is 10. So someone with a mass of 50kg would have a weight on earth of (50 x 10) 500N. But a person with a mass of 100kg on a planet with half the gravity (100 x 5) would also have a weight of 500N.
No, mass is constant all over the earth and everywhere beyond that. Weight on the other hand is a function of mass which depends on the strength of the gravitational pull on the object. Since the gravitational pull from earth isn't constant, but is dependant on what position you are relative to its core, your weight can vary (though its unlikely to be a marked difference).
A mass of 100 pounds, weighs approx 444.5 Newtons. A kilogram is not a measure of weight, a Newton is.
