Answer :
If Jack weighs 156 pounds on Earth then his weight on the moon would be 26.52 pounds.
We can determine Jack's weight on the moon by multiplying his weight on Earth by the difference between the two gravities if the surface gravity on the moon is 0.17 of the surface gravity on Earth.
The first way to get Jack's weight on the moon is to multiply his weight on Earth (156 pounds) by the gravitational ratio between the two bodies. (0.17).
Our total weight is 156 × 0.17 = 26.52 pounds.
Jack would therefore weigh around 26.52 pounds on the moon. This is due to the fact that the gravitational force between two objects is inversely proportional to the square of their separation and directly proportional to the product of their masses.
