The acceleration of free fall on planet X is 1/6 of the acceleration of free fall on Earth. The mass of a body on planet X is 60 kg. What is its weight on planet X?

The gravitational field strength on the surface of planet R is one eighth of that on the surface of planet S. On the surface of R, a body has its mass measured to be 2.5 kg and its weight measured to be 12.5 N What results are obtained for measurements of the mass and weight of the same body on the surface of planet S?

On Planet Phat-Tung, a 50.0 kg barbell can be lifted by only an exerting force of 180 N. What is the acceleration of gravity on planet Phat-Tung? If the same barbell is lifted on Earth, what minimal force is needed?
