Newton’s first Law of Motion of motion tells us that, without this force, the coaster would like to travel in a straight line and at constant speed. This force is called the Centripetal Force. The answer is that there is a force (provided by the rails), that is pushing the trucks of the coaster towards the center of the loop. Why doesn’t a coaster fall off the track when it goes inverted? Why are roller coaster loops not circular?įirst of all let’s go back to basics and understand how a loop works. Let’s take a look and see if we can derive a formula to describe their shape.
Why is this?Ĭlearly there is the same physics and mathematics involved in their designs. They all, also, seem to have the same similar ‘inverted teardrop’ appearance.
Have you noticed that these loops are never circular? Why is this? Many extreme roller coaster these days have vertical loops. I’m going to continue on the roller coaster theme this week. Last week I wrote about the beauty in mathematics and how brachistrochrones might be used in roller coaster designs.
