:grumpy::grumpy::grumpy:It seems that some of the people here are confusing the fact that you are falling with the fact that you can prevent hurting yourself more easily.
You can prevent yourself from falling.
The OP's question is not about a static, unoccupied bike simply sitting on the ground waiting to fall over. The OP's question is about riding a bike, and whether you are less likely to fall over. One cannot "ride" a bike without acting to stay balanced on it.
Simply put, when riding a bike on the Moon, you are less likely to fall over than on the Earth because the act of staying riding is easier.
Dave doesn't get mad; he gets logical. That's far more frightening. I can certainly understand his frustration in this instance. People are trying to counter his knowledge of physics with preconceived notions of how things work based upon terrestrial existence. That irritates me, as well.Don't get all mad, Dave. :)
The coefficient of friction (COF) is a unitless ratio of the horizontal force to push (or pull) an object divided by its (vertical) weight (gravitational force mg) on the moon. Why does the COF change on the Moon?One thing that hasn't been mentioned is tyre grip on the Moon.
It works out that at 1/6 of Eath's gravity (which is what you have on the Moon) the rubber tyre grip goes down to 1/4 of what it would be here on Earth. (not 1/6, because the coefficient of friction goes up by a factor of about 1.43 for a 1/6 load..
