Has the weight of an astronaut with a mass of 70 kg changed on Earth and on the Moon?

The mass has not changed, the mass of an astronaut on Earth is 70 kg, and the mass of him when he arrives in space on a spacecraft is still 70 kg!

The weight has become 1 6 on Earth!

Astronaut body weight on the moon: 72 * (1 6) = 12 kg Reduced body weight 72-12 = 60 kg

First of all, it is necessary to distinguish the difference between weight and mass in physics, and also to distinguish the different definitions of weight in life and physics. In life, weight is expressed in kilograms, while in physics it is expressed in Newton, with a difference of one gravitational acceleration g.

What astronauts lose on the Moon is the weight in the physical sense, because the gravitational acceleration on the surface of the Moon is only 1 6 times that of the Earth's surface, and its own mass is constant. If you ask such a question in the field of physics, I feel that it is a bit contradictory, because the previous sentence says that the weight is only 1 6 on the earth, but then the weight is expressed in kilograms, which is obviously problematic. Because the kilogram can only be used as a unit of mass in physics, not as a unit of weight.

In short, if the unit is kilograms, it means that the question is mass, and the mass is constant everywhere.

It's changed. (The gravity on the Moon is only 1 6 of those on Earth).

The stem of this question is wrong.

An object has the same mass on both the Earth and the Moon, only the weight varies due to the acceleration due to gravity.

The gravitational acceleration of the Moon is one-sixth that of the Earth, so if an astronaut weighs 12 kilograms on the Moon, then he should weigh 72 kilograms on Earth.

The astronaut weighs 12 kg on the moon and 12 kg on Earth 6 = 72 kg;

There's no need to argue about why it's 1 6, it's 1 6 anyway!

Solution: 12x6 72 (kg).

A: The astronaut weighed 72 kilograms on Earth.

The astronaut weighs 12 kg on the moon and 12 kg on Earth 6 = 72 kg;

There's no need to argue about why it's 1 6, it's 1 6 anyway!

∵g=mg

60kg×588n

The gravitational force he was subjected to on Earth was.

The quality does not change with the change of position.

When he landed on the surface of the moon, he had a mass of 60kg

A lunar astronaut has a mass of 60kg, and the gravitational force he experiences on Earth is g=mg=

When he landed on the surface of the moon, he had a mass of m = 60kg

g=mg

60kg×588n

The gravitational force he was subjected to on Earth was.

The mass is a property of the object itself, which does not change with a change in position When he lands on the surface of the moon, his mass is 60kg

The gravity is g month = 1 6mg

60kg×98n

An astronaut on the moon weighs only 1/6 of the weight on Earth, and an astronaut weighs 72 kilograms on Earth, losing zero kilograms on Earth.

This should be an elementary school arithmetic problem, 72*(1 6)=12, use 72-12 = 60 kg, which is the final answer.

But there's a mistake in this question, you don't lose weight, you lose weight, and that's the physical quantity you learn in junior high school, and you can just get to know it.

The astronaut's weight on the moon: 72 * (1 6) = 12 kg

Reduced body weight 72-12=60 kg

You're on Earth 72 and you asked how much Earth there is.

If it's 72 on Earth, then it's 12 on the Moon, that's 60 less

Unit: kilograms.

72 (1-1 6) 60 (kg).

A: On the moon the weight was reduced by 60 kilograms.

The mass of an object is constant, what changes is the gravitational force exerted. Since the quality remains the same, the reduction is naturally 0.

Earth-to-Earth??? I haven't lost weight.

Weight loss refers to the fact that the astronaut is subjected to less gravity, but the astronaut's mass remains the same, and the astronaut returns to Earth at the same weight.

I don't know if the gravity of the 50 kg reduction is based on the Earth or the Moon, but if the Earth is used as the standard, the reduction is f=50 kg*

Let the astronaut weight m, g month = 1 6g ground.

Then there is f=mg-mg-month=490n, and m=60kg

Suppose the astronaut on Earth weighs xkg

Then x-x 6=50

x=60kg

The astronaut mass is constant, what changes is his gravity.

Sixty kilograms, but according to my knowledge, this question is a bit wrong, it shouldn't be said that the weight has decreased, the weight should be the same, what has changed is that his gravity has decreased.

The most crucial point is, what is the name of this astronaut?

1. Reduced by 5 6 * 72 = 60 kg! In fact, the weight itself has not changed, but the measurement environment has changed, resulting in different data displays! ......

2. The number of first prize winners is, 48 (1+2+5)=6

Astronauts weigh 12kg on the moon and 6 times heavier on the moon = 6 * 12 = 72 kg
