Default Jerry Bailey and Physics

I hate to do this... but I cant help myself.

Jerry Bailey: The horse was moving so fast that Centripetal Force took him out not allowing him to cut off the rail.

Centripetal Force is the force that allows the horse to take a turn, it does NOT push a horse out. Inertia keeps the horse wanting to move in a straight line. So blame it on the horse's mass, or intertia, not Centripetal Force.
Centripetal force, in this case is supplied, by friction between the horses hoof and the turf. If a horse tried to take a turn on a frictionless surface (ex.something like ice) it would be unable to do so, no turning without friction in this case.

And I thank you. A public service announcement.

Common misunderstandings:

Centripetal force should not be confused with centrifugal force. The centrifugal force is a fictitious force that arises from being in a rotating reference frame. To eliminate all such fictitious forces, one needs to be in a non-accelerating reference frame, i.e., in an inertial reference frame. Only then can one safely use Newton's laws of motion, such as F = ma.

Centripetal force should not be confused with central force, either. Central forces are a class of physical forces between two objects that meet two conditions: (1) their magnitude depends only on the distance between the two objects and (2) their direction points along the line connecting the centres of these two objects. Examples of central forces include the gravitational force between two masses and the electrostatic force between two charges. The centripetal force maintaining an object in circular motion is often a central force.

I'm glad we have some physics professionals on here to clear that up....

I've learned somethings I didn't know in this thread....

However, I'm not so sure I really wanted to know this information. It might clutter up the limited space my brain allotts for me to remember more important information.

Such as the name of the stripper who gave me an extra kinky lap dance a few months ago.
