The orbit is called a train. A constant height from the ground up in the air after you install the restraints, restraints on the rails 42 to connect the rail to be run over by a train ohreunaerimyeo says. The horror and amusement park rides, railway trains, black holes, galaxies, etc. is called a roller coaster all the train tracks.

The train rises to the height of the spiral to swing binggeulbinggeul bakwissik inverted to round, yet he's hanging upside down without falling, and vice versa does not map out the centripetal force twieonaga (求心力) and the centrifugal force (远心力) to effect the principle of said.

The centripetal force deungsokundong (等速运动) and work toward the center of the circle to the jiljeom is power, the centrifugal force in a circular motion and centripetal force and the size of objects that appear in the same direction as the inertia that is the opposite. That is receding from the center of the circle, the direction of centrifugal force, the centripetal force acting toward the center of the circle.

Some people train on a roller coaster ride, depending on the rotation of the rotary power to take a protruding outside the circle, the power to act, even when upside down it does not fall below that of the centripetal and centrifugal forces is to achieve equilibrium.
