Gravitational force on the surface of the moon is only 1/6 as strong as gravitational force on the earth. What is the weight in newton’s of a 10 kg object on the moon and on the earth?

Solution:

Given data:

Acceleration due to earth’s gravity = g_e or g = 9.8 m/s²

Object’s mass, m = 10 kg

Acceleration due to moon gravity = g_m

Weight on the earth= W_e

Weight on the moon = W_m

Weight = mass x gravity

g_m = (1/6) g_e (given)

So W_m = m g_m = m x (1/6) g_e

W_m = 10 x (1/6) x 9.8 = 16.34 N

W_e = m x g_e = 10 x 9.8

W_e = 98N
