An astronaut has a mass of 60 kg on Earth. What is the astronaut's mass on the Moon, where gravity is about one-sixth as strong?

Explanation

1. 01

   Mass is the amount of matter in a body; it does not depend on where the body is.

2. 02

   So the mass stays 60 kg. Only the weight falls to about one-sixth, from about 588 N to about 98 N.
