WHY DOES A COIN STAY UP WHILE SPINNING INSTEAD OF FALLING OVER?
THE ANSWER ALSO IS NOT GRAVITY BUT IT STARTS WITH A G MY TEACHER SAID SO

Gyroscopic principle...it uses the cetriptal forces to stay balanced. Gyroscope are used in many forms including avionics and navigation. They sell these as "toys" in stores that sell more education based toys. You can make it balance on a pencil tip.
BTW..for the gentlmen above...cetrifugal force does not push out...it pushes in. Interia pushes out. The balance of the two create the circular motion.

Because the GYROSCOPIC FORCES attempt to keep the coin spinning exactly as it is. Friction exists in real life, and friction will begin to slow down the spin until the gyroscopic force that held it upright falls below the forces of GRAVITY and the coin will flop over completely.

It's not a G. It's centrifugal force. When something spins, the mass is pushed at all angles evenly, so it goes!!
When slowing down, it losses momentum, so it gets tipsy and falls.

it's the scientific law:
A body in motion stays in motion, until something interferes with it. You start the coin rotating...then gravity pulls it to fall.
(if it's not gravity, it might be g-force...)

Just to clarify something, Scooby, you're wrong. Centripetal force is the inward force. Centrifugal force is the reactionary force to centripetal (meaning it is an outward force) but it is a pseudo force.
What we "feel" is centrifugal force, but the force that really exists is the inward centripetal force.

Your teacher lied, its because of centrifical force, unless your teacher just has a really bad accent.
