when the ride goes through the loop it performs circular motion, the most important thing that ride must have is that sufficient amount of kinetic energy so that it will be able to complete the circular motion , while performing the circular motion at the top of the circular path the forces that are present are weight which is vertically downward, normal force by track gain vertically downward, and finally the centripetal force which is vertically upwards to compete this circular path this centripetal force must be equal or greater than the sum of weight and normal force.
