On the Moon, the gravitational field strength is 1.6 N/kg.
How much would an 80 kg equipment pack weigh on the Moon?
Use the equation:
weight=mass×gravitational field strength \text{weight} = \text{mass} \times \text{gravitational field strength} weight=mass×gravitational field strength50 N50\text{ N}50 N
81.6 N81.6\text{ N}81.6 N
128 N128\text{ N}128 N
800 N800\text{ N}800 N
