It probably is because of the engine the pulls the coaster to the top
Centripetal force is the force that keeps you in your seat in the rollercoaster. It is the force that pulls toward the center of a circle when anything is in curved motion.
When there is that force that pulls downward. Example, when you climb a mountain. You will fell that there is that gravity pulling downward.
It is the earth's gravity.

Newton's second law (Force equals mass times acceleration, F = ma) deals with acceleration so it "takes effect" every time that the roller coaster speeds up, slows down or turns (horizontally or vertically).Basically Newton's second law just says that the acceleration of an object is directly proportional to the net force applied to the object and inversely proportional to the mass of the object. Or, in other words, the harder you push the faster it speeds up and the bigger it is the slower it speeds up (or slows down - deceleration is an acceleration).This means that in your roller coaster example, the object is the roller coaster and the force can be: The motors that start the coaster and lift it up hills. The brakes that slow it down. Gravity which pulls it down the hills. The rails and wheels which cause the roller coaster to turn around bends, etc. At each of these points, Newton's second law is at play, determining how much acceleration will result from the force applied to the roller coaster's mass.

Well, to understand what a roller coaster does you will need to understand what a roller coaster is. A roller coaster is a small vehicle that runs along a fixed track. What a roller coaster does is move along that fixed track at very high speeds, and many people find this very thrilling And if your wondering how a roller coaster works Well, there are 2 types of roller coaster, most commonly the Chain Lift, The chain lift works by hooks on the bottom of the roller coaster car that hook on to a roller chain (the type of chain you would find on a bicycle) and the chain pulls you all the way to the top of the big hill, This is the part where you hear all the clicking. As you start going down the big hill the hooks simply slide out of the chain and gravity starts to take over, but the roller coaster can stay moving because of Kinetic energy and Potential energy. So the 3 things that are very important to a Roller Coaster are Kinetic energy, Potential energy, and gravity. A roller coaster works sort of like rolling a ball down a hill.

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)
