What is the mass on the moon where the force of gravity is 1/6 that of the earth?
Its mass is still 50 kg but the Moon’s gravitational pull is only about 1/6 of the Earth’s – in other words about 1.6 N/kg. This means that the weight of our crate on the Moon will be 50×1. 6 = 80 N and so it will be much easier to lift up.
