Question

take weight of five of your friends find out what their weights will be on moon and the Mars

Answer 1

their weight will be decreased because there will be no gravity on moon and mars

Answer 2

The weight of an object is dependent on the gravitational pull force.The amount of gravitational pull force is directly proportional with the weight, which means if the gravitational pull force increases the weight will also increase accordingly.

The gravitational force in the moon is almost 1/3 than the earth's gravitational force.

on the other hand gravitational force in the moon is almost 62% less than the earth's gravitational force.

And wait in the moon and the mars will also be decreased according to the decrease of gravitational force than the earth.
