A roller coaster is an entertainment facility with high-speed motion and exciting experiences. So, how a roller coaster works? If you’re shopping for a roller coaster for your amusement park, you can start by learning how it works. How it works involves several concepts and principles from physics. We are a professional manufacturer of amusement equipment. Here we explain to you how the roller coaster works.


The working principle of the roller coaster is based on the law of energy conversion and conservation. The high-speed motion of the roller coaster is due to the conversion of potential energy into kinetic energy. The kinetic energy is then converted into other forms of energy.

  • Starting point:

    The operation of a roller coaster usually requires a slope called a starting ramp. When passengers ride the roller coaster and prepare to launch, the roller coaster is pushed to the highest point of the starting ramp. This high point is usually the highest point of the entire roller coaster track. At the highest point of the start ramp, the coaster has its greatest potential energy. Potential energy is generated due to the height of the roller coaster. It can be converted into kinetic energy by sliding down.

  • Gravity and Kinetic Energy:

    Once the roller coaster reaches its highest point, it will slide down. Sliding down is due to gravity. According to the effect of the earth’s gravity, objects have more potential energy at high places and more kinetic energy at low places. As the roller coaster slides, its potential energy is gradually converted into kinetic energy.

    The design of the roller coaster makes the kinetic energy increase continuously and the speed gradually increase during the descent. The shape and inclination of a roller coaster track cause its speed to increase. Each part of the track is designed to have different heights. So the roller coaster can maintain a relatively constant speed when sliding down.

    As the roller coaster descends, the kinetic energy gradually builds up enough to allow the roller coaster to complete a complete loop of the track. When the roller coaster reaches the lowest point of the track, its kinetic energy is at its maximum. At this point, the roller coaster will enter a series of turns and ups and downs. So it can provide excitement and entertainment for tourists.

  • Braking system:

    As the roller coaster completes a full loop of the track and begins to slow down, kinetic energy is gradually converted into other forms of energy. Typically, the braking system slows down the coaster. The brake system can be friction brake, magnetic brake or hydraulic brake, etc. The goal of the braking system is to gradually convert the kinetic energy of the coaster into heat and eventually dissipate it. This is to ensure that the roller coaster can come to a safe stop as it nears the finish without overshooting or creating a hazard.
