Choose the correct physics terms which can be used to describe how roller coasters work. On a traditional roller coaster, the train begins by going slowly up a steep slope at the start of the track. Generally, the train is pulled up this slope by a moving chain located below the track, which is driven by an electric motor. When the train reaches the top of the slope, it has This means it has the ability to descend due to the force of gravity. Therefore, the train can now produce (that is, movement) without needing more power from the motor. The next section of track has a steep downward slope. This allows the train to increasing its as it goes down the slope. This, together with the mass of the train and passengers, gives the train enough to coast for a fairly long distance, without power. The rest of the track can include upward and downward slopes, curves, loops and corkscrews. These exert forces of resistance, which progressively cause the train to These forces are: gravity, causing resistance as the train goes up slopes the resistance of the wheels rubbing against the track and against their bearings and axles. This converts kinetic energy to increasing the temperature of the wheels. Roller coasters do not only have wheels running on top of the rails. They also have 'upstop wheels' below the rails and 'guide wheels' at the sides of the rails, to hold the train on the track. On sections of track with curves and loops, friction is greatly increased by which tries to push the train outwards as it turns. This presses the wheels hard against the track, generating high frictional resistance and, as a result, high temperatures. This force also pushes the passengers into their seats, generating the that roller coasters are famous for.
