The gravitational field of the Moon at its surface only
Of course as the Apollo 16 astronaut John Young demonstrates, you cannot jump easily on the moon with the massive spacesuit and
environmental back pack added to your 'shirt sleave' mass. Although your weight is 1/6 what it is on Earth, you still
have to work against the inertia of all that mass.Typically the suit plus backpack had a mass
of 90 kilograms or nearly 200 pounds added to the astronauts own mass. Also, jumping on the moon with a spacesuit
is a very scarry proposition because of the center-of-mass not being in the midplane of your body but shifted towards your back, making the balancing
a very tricky maneuver.

983 cm /sec/sec
or about
1/6th of what we feel on the surface of Earth in terms of the acceleration of
gravity, so this means that for the same energy expended, you should be able
to jump about 6 times higher. I can jump about 20 inches, so that means on the
Moon I could jump 6 x 20 = 120 inches or 10 feet straight up!
