About 700N
70kg • 10m/s = 700N

Why can an objects weight vary with location but its mass cannot?
Mass is an inherent property of an object and it does not change. Most commonly, we weigh objects on the earth. An object's weight depends on the attraction by gravity to another object. The formula for weight on the earth is weight = (a constant) x (mass of object) x (mass of earth)/(d-squared) where d = distance between center of mass of object and center of mass of earth d-squared is the distance d, raised to the second power. A person weighs slightly less on the top of a mountain than they weigh at sea level. Because moon's mass is only about one-sixth the mass of the earth, the weight of a man on the moon is about 1/6 of his weight on the earth.
Why will a person's mass never change whether they are on earth or on the moon?
Because mass is not the same as weight. Weight is mass times gravity so your weight will change if you are on the earth or moon but your mass will stay the same.
Why is the mass of an object the same on the moon as it is on earth but the objects weight is different?
That is because Earth has more gravity. Weight = mass x gravity.
What is the mass of 1200 mg?
At the surface of the earth, mass = weight, so 1200 mg weight = 1200 mg mass
What is your weight and mass on earth if you way 40 kg?
40kg of mass, 400 (approx) N of weight.
An astronaut on the moon has the same mass as she did on earth but has less?
mass doesnt change but weight does
What happens to the mass of an astronaut when he is on the moon?
Nothing, but his weight is 1/6 of his weight on Earth.
What is the mass of an astronaut on earth?
In everyday usage, mass is often interchangeably with "weight". Every astronaut is different, just like everybody else.
Is the mass of an astronaut more or less on the moon or on earth?
The mass of an astronaut remains the same whether they are on the moon or on Earth. Mass is a measure of the amount of matter an object has and is independent of the gravitational force acting on it. However, the weight of an astronaut would be less on the moon compared to Earth due to the moon's weaker gravitational pull.
Between mass and weight the more fundamental quantity is?
Mass. Weight is different depending on gravity, but mass is always the same. On the Moon an astronaut weighs less, but has the same mass that they have on Earth.
What is the weight of a 90 -kg astronaut on Earth?
On Earth, 90 kg of mass weighs 882 newtons (198.4 pounds).
What has changed to cause the weight of the astronaut to be different?
weight= mass*gravity in this case, an astronauts mass has stayed the same, but the gravitational force acting upon him has decreased, decreasing his weight. gravity decreses because the astronaut is further from the centre of gravitational attraction (the earth)
Why would an astronaut weigh less on the moon than earth?
The moon is considerably smaller than the Earth, both in diameter and in mass, and it therefore has a much weaker gravitational field. The weight of an astronaut on the moon is the result of the mass of the astronaut, which is not changed by going to the moon, and the gravitation field of the moon. A weaker gravitational field produces a lower weight.
Why does an astronaut weigh less on the moon that on earth?
Your weight is a function (G=mg) of the gravitational pull (g) and the mass of the object in question (m). The mass of the Moon is only 1/6 that of Earth, so the astronaut on the Moon weighs only 1/6th as much as he does on Earth. His mass does not change.
What is the difference between the astronaut's mass on the earth and on the moon?
There is no difference in an astronaut's mass no matter where he or she might be. Mass is a constant, as opposed to weight which is dependent upon acceleration.None.Put simply. Mass is a measurement of how much matter is in an object, whereas weight is a measurement of how hard gravity is pulling on that object. As their is less gravity on the moon, your weight would be different, your mass would not.
How much will astronaut weigh in outer space?
A pound is a unit of mass. Mass is constant throughout the cosmos, so if the astronaut has a MASS of 180 pounds on Earth, it will be the same even in space. But, the astronaut doesn't have a weight of 180 pounds. His MASS is 180 pounds. Weight = mass x gravity. So, in space, his weight is 0 Newtons.
Would your weight increase on the moon?
No. As long as you continued to eat your astronaut food and do your astronaut exercises, your weight would remain constant on the moon. But it would only be about 16% of your weight on Earth. Your mass would be the same on the moon as it is on Earth, and would also not change while you're there.
