Question

The gravity on Moon is about 1/6 of the gravity on Earth.  If a person weights 120 lb on Earth,

 

His weight on Earth, in unit of Newton, is:                      (Hint: 1 lb = 4.45 N)                     

  1. 0 N                           27 N                     c.    89 N                     d.   534 N       

His mass on Earth is:  (Hint: Weight = mass×9.81 m/s2   or             mass = Weight ÷ 9.81 m/s2)

  1. 265 kg                     54 kg                     c.   9.1 kg                    d.   0 kg           

How much does he weigh on Moon?                                                                                     

  1. 720 lb                     120 lb                    c.    20 lb                     d.   0 lb

 

His mass on Moon is:

  1. 265 kg    54 kg                     c.  9.1 kg                     d.   0 kg
