Gravity on the surface of the moon is only 1/6 as strong as gravity on the earth. what is the weight of a 19 kg object on the earth? the acceleration of
gravity is 10 m/s2
answer in units of n.
(part 2) 10.0
what is the weight on the moon?
answer in units of n.

The weight of anything in any place is

         (mass of the thing) x (acceleration of gravity in that place).

-- On Earth, the acceleration of gravity is about  9.807 m/s²

Weight of 19 kg of mass is  (19 kg) x (9.807 m/s²) =  186.3 newtons

-- On the Moon, the acceleration of gravity is about 1.623 m/s²

Weight of the same 19 kg of mass is  (19 kg) x (1.623 m/s²) = 30.8  newtons

Less force and energy was applied

A. to determine if humans can explore mars safely
