This doesnt make sense, what does this have to do we Osama?

WHY NOSAMA?

Well see it all has to do about Newtons Laws of Motion. Mostly inertia and gravity... (I dont know if this is right it just makes the post that _______ made below me look bad. I had to reply to you).

*__________, and yeah, you're making me feel just a bit bad. I wish this had been the first comment. It's ok, though.

Ever heard of physics?

by Anonymous 14 years ago

Because of inertia. A wheel by itself falls but if you roll it it rolls upright, keeping in balance. Standing it has the tendency to fall since it hasn't really any form or position, but moving it has the position of being exactly upright and moving forward, and it would need force to make it not be upright anymore or to change direction.

ever heard of centripetal force??

by Anonymous 14 years ago

Lolno, centripetal force is what makes the planets stay in orbit, it's not just the force of any circular things. Spinning a ball around you on a string is centripetal force, but wheels on a bicycle have nothing to do with it.

wow...you've obviously never taken a physics course. don't try to make it sound like you know what you're talking about because i know i'm right.

by Anonymous 14 years ago

Ditto (except with proper grammar).

Spinning a ball on a string is centrifugal force or inertia, they're the same thing

by Anonymous 14 years ago

spinning a mass on a string is centripetal force too, but there's not just one form...bike wheels also exibit centripetal force when they are in motion. this is why the faster you go, the harder it is to fall.

If you were hugging a tether ball (I don't know what other reference to use with you) and riding a bike at the same time only then would the bike have centripetal force. The wheels moving in a straight line aren't under centripetal force.

Spinnig a mass on a string is centrifugal force, whisk is quite different from centripetal force

by Anonymous 14 years ago

If they were the same thing they wouldn't have two different names with separate and own articles in any science book.

Inertia cause centrifugal force because the ball tries to stay going straight, but the string stops it

by Anonymous 14 years ago

Onoway man, thanks so much I obviously didn't know either of those two and was just arguing this for shits and giggles. I KNOW what the two mean, and they ARE two, they're not the same thing is what I said. Your previous comment said centripetal force(and learn to spell this please) causes the bicycle to keep going and keep balance, while the vehicle moving in a straight direction is not centripetal force at all. Sure, there might possibly be some on the wheels in a situation, but wheels being part of a system do NOT make inertia acting upon it just turn into centripetal force.

Actually centripetal and centrifugal forces are different things, how about you learn basic physics

by Anonymous 14 years ago

Oh lol, I apologise. I do feel stupid now, for that mistake. That still doesn't make you right though. Centrifugal force is closely similar to centripetal, and none of the two have to do with a bicycle riding forwards. Both the forces need an axis around which to spin -- centripetal force leaning towards the axis and centrifugal from -- and a bicycle is going a straight direction. At zero speed it has zero inertia to keep standing, and while it is moving it's got great inertia of the great speed of rotation of the wheels.

centrifugal force doens't exist. it physically can't. i don't remember why, but i remember my physics teacher telling me that.

by Anonymous 14 years ago

Oh, see, that is probably the problem. Your physics teacher is an idiot. That's why you're arguing something completely untrue (whether or not it has to do with centrifugal force). Centrifugal force is the force the string connected to the pole has while the tether ball is circling. Centripetal force is the force that keeps the tether ball circling while it wants to go in a straight line.

your right that neither have to do with a bike, but I never said they did all it is is gyroscopics

I give up.
