A mass of 70.0kg on earth, what would their mass be on the moon, which has 1/6 the gravity of earth

70 kg

Explanation:

We are given;

Mass on the earth = 70 kg Gravity on the moon = 1/6 earth's gravity

We are required to determine the mass on the moon's surface.

We need to know that the mass of an object remains constant and is not affected by the gravitational pull of a surface.

Therefore, and object with a mass of 70 kg on the surface of the earth will still have the same mass on the surface of the moon.

Therefore, the mass on the moon's surface will still be 70 kg
