What is the approximate weight of a 20-kg cannonball on the moon if the acceleration due to gravity is 1.6m/s^2

On Earth, a cannonball with a mass of 20 kg would weigh 196 Newtons.

With the formula F=mg, where F is the weight in Newtons, m is the mass, and g is the acceleration due to gravity on the Earth which is 9.8m/s^2.

F=20kg x 9.8m/s^2 = 196 Newtons

BUT on the moon, acceleration due to gravity is 1.6 m/s^2,

so F=mg=20kgx1.6m/s^2 = 32 N
