Gravitational field strength x mass = weight. Weight is measured in Newtons.

Question 3

Will you have the same weight on different planets?

Answer 3

No - all the gravitational field strengths on different planets are different.

Question 4

Will you have the same mass on different planets? (Mass is measured in kg)
