Answer:
<em>Due to gravitational force</em>
We know that,
weight (W) = m. g Newtons
Where m = mass , in Kg
g = gravitational force (m/s²)
= 9.8 m/s (it is constant on earth)
<em> So, from equation we knew that Weight is proportional to the gravitational force assuming fixed mass.</em>
<em> On the moon the gravitational force (g) is very less compared to the earth gravitational force, i.e., </em><em>1.62 m/s²</em>
<em> Therefore from equation of weight</em><em> W = m. g</em><em> is very less by considering the gravitational force on moon.</em>
So, obviously weight changes on moon due to gravitational pull
