Roller coaster rides create a lot of G force, pushing your body up or down when the roller coaster falls or climbs quickly. This force puts a lot of pressure on your back while riding, and can compress spinal discs. Basically, roller coasters crunch your back, and a are a bad idea if you already suffer from back pain.
G force is the gravity force. When you go up on a swing and at the highest point you feel weightless, that is negative g force. When you are in one of those rides that makes you feel super heavy (or when you're at the bottom of a big hill on a roller coaster) that is positive g force. Both negative and positive g force can kill you. Positive g force makes blood have a hard time getting to the brain and negitive g force makes it too easy to get blood to your brain. Before you die, you throw up, then pass out. Don't worry about going on roller coasters though. In the USA rides are only alowed to have 3.5 g force each way (i think, can someone check my numbers?) and you throw up at 5 g force each way and at 10+ g force each way you pass out.

No. Roller coasters run on gravity and G force. The nearest type is the one who puts the rider on the track with the chair below the track and their feet dangle in the air.
I suppose you're talking about the loop-dee-loops? It's G-Force. The bar helps also. :)
Yes, there is a difference between positive and negative g-force. Positive g-force is the sensation of weight pressing down on you, like during takeoff in an airplane. Negative g-force is the sensation of weightlessness or forces pulling you away from an object, like in a roller coaster drop.
That is because the roller coaster is designed to accelerate you with enough force to experience more than 1G acceleration. When upside down you are being pulled down with 1G but up with more than 1G so net force is up, not down. Some rides give you 2-3 G up force.
G means effective gravity caused by the velocity (acceleration and direction of travel) induced upon a body. In the case of a roller coaster the person is the body. 1 G is the effects of gravity regularly. If a roller coaster pulls 2 G this means the effect of gravity is twice the normal and therefore will react by causing the body to be weigh more (weight = mass x gravity)
