It is present everywhere.
the gravity will pull the roller coaster down a little bit and then it might go a little slower.

Gravity
A roller coaster increases kinetic energy when it is going downhill, as gravity is pulling it down and accelerating it. The potential energy is converted into kinetic energy as the roller coaster gains speed.

It depends on which type of roller coaster. Some of then use a magnet to get their speed. Other use a pressure, or they just let gravity do all the work.
gravity and momentum
the two forces are friction and gravity
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)
