a walking motion due to the lack of gravity (a raised foot while walking would be suspended six times longer than it would be on
Earth). The most efficient way to walk is to lope: putting one foot before the other, pushing off with this foot, and landing on the
other, but not separating the feet as in a normal stride.
Stopping and starting is easier for heavier people, as those carrying less weight (SIZ 50 or less) find starting and stopping
momentum harder. Grip on the lunar surface is a matter of friction, and low gravity means there is less friction and less grip. An
investigator attempting to run normally would end up tumbling over onto their faces, while attempting a quick stop means they
skid uncontrollably.
Gravity being 1/6th that of Earth’s, a successful Jump roll indicates a height of up to sixteen-feet on the Moon—on Earth, an
average jump height would be 16–20 inches, from standing. An unsuccessful Jump roll indicates a maximum height of ten-feet
is gained.
