an man has a mass of 80 kg on earth.


What is the mass and weight while on moon? Explain your answer​

Answer 1

Explanation:

13.333 kg..................

Answer 2

We would take the mass given, 80 kg, and multiply it times the acceleration of Earth's downward pull on that mass, 9.8 m/s/s.

784 N = 80 kg x 9.8 m/s/s

So the weight on Earth is 784 newtons.

Now the gravitational attraction of the moon is about 1/6 that of the Earth, or about 17%. To calculate the weight on the moon, simply multiply 784 N times .17, or 17% in decimal form:

784 N x .17 = 133.28 N

So the weight of the same 80 kg mass on the moon is 133.28 N.
