Do roller coasters use mechanical energy?

All moving objects possess kinetic energy, which is determined by the mass and speed of the object. In a roller coaster, the forms of kinetic are mechanical, sound and thermal. Potential energy is the energy an object has as a result of its position. Potential energy is stored energy that has not yet been released.

The first hill of a roller coaster is always the highest point of the roller coaster because friction and drag immediately begin robbing the car of energy.

Mechanical failures can be due to the design flaw, lack of maintenance, latch failures, or the failure of the other structural components, which can lead to the catastrophes. In some cases, the nature of the ride itself can cause detrimental injuries to the riders.

Potential and kinetic energy can be exchanged for one another, so at certain points the cars of a roller coaster may have just potential energy (at the top of the first hill), just kinetic energy (at the lowest point) or some combination of kinetic and potential energy (at all other points).

A roller coaster demonstrates kinetic energy and potential energy. A marble at the top of the track has potential energy. When the marble rolls down the track, the potential energy is transformed into kinetic energy. Real roller coasters use a motor to pull cars up a hill at the beginning of the ride.

Roller coasters are driven almost entirely by basic inertial, gravitational and centripetal forces, all manipulated in the service of a great ride.

At the bottom of the loop, gravity and the change in direction of the passenger's inertia from a downward vertical direction to one that is horizontal push the passenger into the seat, causing the passenger to once again feel very heavy.

Engineering a roller coaster brings together many engineering disciplines, including mechanical engineering to design, implement, and maintain the ride and ensure it is safe, and structural engineering to guarantee the attraction can withstand the elements.

According to Kevin Hickerson, a physicist at the California Institute of Technology, “All the energy a roller coaster gets comes from the initial point it's cranked up to, and from there it just gains more and more kinetic energy.” The height of this first drop also determines the speed of the coaster cars.

MORE DETAILS

Gravity applies a constant downward force on the cars. The coaster tracks serve to channel this force — they control the way the coaster cars fall. If the tracks slope down, gravity pulls the front of the car toward the ground, so it accelerates.
