Question

If a person weighs 809 N on the Earth, what is the person's weight on the Moon?_____ N

Answer 1

Answer::

the person weight -809 N

Twe know the gravity on earth a=g= 9.8 m/s²

i know this formula F=ma = mg................(1)

according to question

F=ma

809=m * 9.8

m=82.55 kg

the mass of person m=82.55 kg which is not change

mass always same mass is constant mass will  never changed

but gravity always changed

if a object weight 1/6th weight of earth this is normal  not practical

accurate calculation ,

the gravitation of moon is =1.6 m/s²

^{and weight of person on moon= mass*gravity}

=82.55 * 1.6 N

=132.08 N

THE mass of person is 82.55 kg but weight on the eartH is 132.08 N
