Q. 12 . Gravitational force on the surface of the moon is only as strong as gravitational force on the earth. What is the weight in newtons of a object on the moon and on the earth?
The weight of an object on earth is given by w = mg where m is the mass of the object and g is the gravitational acceleration.
g = 9.8 m s-2
Weight of a 10 kg object on earth = 10 X 9.8 = 98 N
As gravtitaional force on the surface of moon is only 1/6 th of that on earth the gravitational accelerationn on moon would be equal to g/6.
Weight of an object of mass 10 kg on moon is therefore given as follows
