what is the weight on the moon of an astronaut who weighs 180 pounds on earth?

30 pounds.


...

150/25 =6, so an astronaut weighs 1/6 of their earth weight when on the moon, so 1/6 of 180 = 30 pounds.

Thx!

Your weight on the moon is a function of the moon's gravity. First, we know that gravity is a force that attracts all physical objects towards each other (but why this happens is largely unknown!). Second, the greater the mass of an object, the stronger the force of gravity.

The moon is 1/4 the size of Earth, so the moon's gravity is much less than the earth's gravity, 83.3% (or 5/6) less to be exact. Finally, "weight" is a measure of the gravitational pull between two objects. So of course you would weigh much less on the moon.
