Does a roller coaster lose energy due to friction?

The force of friction acts on the moving cars, decreasing the total amount of mechanical energy in the system. The mechanical energy is not lost, however. It is transformed into thermal energy, which can be detected as an increase in the temperature of the roller coaster's track and car wheels.

Because of friction between the coaster cars and the track, along with air resistance as the cars move forward at high speed, the amount of mechanical energy available decreases throughout the ride.

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. If the tracks tilt up, gravity applies a downward force on the back of the coaster, so it decelerates.

On a roller coaster, energy changes from potential to kinetic energy and back again many times over the course of a ride. Kinetic energy is energy that an object has as a result of its motion. All moving objects possess kinetic energy, which is determined by the mass and speed of the object.

MORE DETAILS

A few kinds of motions in a roller coaster are static friction, rolling friction and acceleration. Static friction is friction that occurs between two surfaces that aren't moving. Rolling friction is the friction that occurs between the wheels and the track.

Roller coasters rely on gravity to take them to the end of the track. This involves two types of energy, potential energy and kinetic energy.
