A person weighs 780N on earth. What is his mass on earth, mass on moon? What is his weight on the moon?

79.6kg  

127.5N

Explanation:

Given parameters:

Weight of the person on earth = 780N

 Now, we are to find;

Mass on earth;

Mass on moon;

Weight on moon

Solution:

The mass on earth and on the moon are the same. Mass is the amount of matter in a substance.  

   Weight  = mass x acceleration due to gravity

     780  = mass x 9.8

           mass  =   = 79.6kg

Mass on earth and moon  = 79.6kg  

The acceleration due to gravity on the moon is 1.6m/s²

  Weight on moon = 79.6 x 1.6  = 127.5N
