It would not move
the gravity will pull the roller coaster down a little bit and then it might go a little slower.
It is present everywhere.

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.
