What is the weight in newtons of a eighty kg person on moon?

Answer 1

Force is equal to mass times acceleration, so in this example, the force in question is that due to gravity, aka weight. And since we are talking about the force due to gravity, we must include the acceleration due to gravity on the moon as well. so you substitute those variables into the F=m*a to get W=m*g, where g is the acceleration due to gravity on the moon. Make sure the acceleration is given in m/s^2, and not other units, otherwise your units will not match..

I know the gravity is about one-sixth of earths, and the weight of an 80 kg person on earth is 80*9.81=784.8 N. so the answer to your question should be about 784.8/6= 131 N.

Answer 2

The acceleration due to gravity on the moon is about 1.6 m/s^2, which is about 1/6th that of Earth's gravity. Therefore, the weight of an 80 kg person on the moon would be approximately (80 kg) * (1.6 m/s^2) ≈ 128 N.
