An object's weight on the Moon is less than its weight on Earth. This is because the Moon exerts less gravitational force on an object than Earth does. The equation

m =

can be used to find an objectżs weight on the moon, where m is the objectżs weight on the Moon, and e is its weight on Earth.

If a rock weighs 120 pounds (lb) on Earth, which of the following is the best estimate of the rock's weight on the Moon?

You failed to provide either the equation or the "following" choices.

I am assuming the equation is

m = e/6.

That would imply that m equals one-sixth of 120 pounds.
