As popular as Ultimate Frisbee is, maybe Interplanetary Frisbee is the next step for the sport.
Asked by: Jonathan Hinchliffe, Birmingham
Since the Martian atmosphere is about 100 times less dense than Earth’s, the ‘lift’ a frisbee experiences would also be about 100 times less. But the gravitational force on Mars is about a third of that on Earth, so a frisbee on Mars would act as if it is about 33 times heavier (100/3). Since the lift depends on the size of the frisbee, the angle of attack and the velocity it is thrown (as well as the air density), it would still be possible to make a frisbee glide, but it would require much more effort on the part of the thrower!
