Some teens asked me a "what if" question here it is Lets say a person is travel at the speed of light of holding a flashlight behind him could he see the light coming from the flashlight? My logical answer was no because the person would be in front of light Where as my friend who...

"If You Dropped a Corn Kernel From Space, Would it Pop During Re-Entry?" This wacky question way emailed to the magazine Popular Science insufficiently answered in Jan 2009 p.80 is it possible to figure mathematically this out without testing it

I am in need of a proper mathematical interpretation. If I am correct than their is a equation in which I can change the only the tire size and the velocity of GoPed will not change. Not being mathematically inclined i do not know how to do this.

The only thing a that changes by changing the tire size is the RPM and torque of the tire

In theory they will get there the same time

ok when i said 2in and 4in tire i meant circumference i was thinking about distances traveled

i am not good with the math and i have my ratios wrong

then my datas wrong

Changing the tire size on a GoPed DOES Change change the gear ratio. If you to use a pinion and sprocket to model a example the tire is effectively also the sprocket you can't cant change one without the other like you can on a passenger car.

The tire is effectively no more than a idler gear between the the spindle and the ground and its size is irrelevant, correct?

Yea I am visualizer understanding Ranger Mike's equation does not come natural to me. here's how I did the math on thanksgiving. The numbers and circumference are simple just for the sake of simplicity Spindle has a circumference of 1in and is spinning at 100 RPM. I feel its safe to say that...

Thanks Danger and sorry for the double post my friend is Physics Major(which is why i want to move my question here) with a minor in mathematics. I am gonging against him and every one else engaged in the discussion plus a university physics professor that was suppose to settle it. My friend...

Ok my friend and I are having a disagreement about gearing on a GoPed. I am stating that if you change the tire size of a California GoPed the speed of the GoPed will not change. This is all theory so am not taking into account friction, mass or the like. For those of you who do not how a...
