On the surface of the Moon, a 91.0-kg physics teacher weighs only 145.6 N. What is the value of the Moon’s gravitational field at its surface?

1 answer

weight = m g
145.6 Newtons = 91.0 kg * gmoon
gmoon = 145.6 / 91 = 1.6 m/s^2

so by the way
gearth / gmoon = 9.81 / 1.6 = 6.13
he would weigh about 6 times as much on earth :)
