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?
weight due to the moon's weaker gravitational pull. The force of gravity is determined by the mass of the objects involved and the distance between them, so being on the moon, which has less mass than Earth, results in a weaker gravitational force.
What happens to the mass of an astronaut when he is on the moon?
The mass of an astronaut remains the same on the moon as it does on Earth. Mass is a measure of the amount of matter in an object and does not change based on location. However, the astronaut's weight would be less on the moon due to the moon's lower gravitational force compared to Earth.
What is the mass of an astronaut on earth?
The mass of an astronaut on Earth would be the same as their mass in space. Mass is a measure of the amount of matter in an object and does not change with location. It is the weight of the astronaut that would vary depending on the gravitational force acting on them.
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.
What is the weight of a 90 -kg astronaut on Earth?
The weight of a 90-kg astronaut on Earth would be approximately 882.9 Newtons (N). This is calculated by multiplying the astronaut's mass (90 kg) by the acceleration due to gravity on Earth (9.81 m/s^2).
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?
An astronaut weighs less on the moon than on Earth because the gravitational pull on the moon is about one-sixth that of Earth's. This means that there is less force pulling the astronaut down, resulting in a lower weight measurement.
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?
An astronaut's weight in outer space would be close to zero because they are in a state of free-fall or microgravity, causing them to feel weightless. Weight is a measure of the force of gravity acting on an object, so without significant gravity in space, an astronaut would not experience weight as they would on Earth.
Would your weight increase on the moon?
No, your weight would decrease on the moon compared to Earth because the moon has less gravity pulling on you. Your mass would stay the same, but since gravity is weaker on the moon, you would weigh less.
How would the weight and mass of the rocks on earth compare to measurements the astronaut made on the moon?
