Lifting an object on the moon requires one-sixth the force that would be required to lift the same object on the earth because gravity on the
moon is one-sixth that on earth. What about horizontal acceleration?
If you threw a rock with enough force to accelerate it at 1.0 m/s2
horizontally on the moon, how would the required force compare to
the force necessary to accelerate the rock in the same way on the
earth?
