Hey kids, tell me how do u feel when you ride a roller coaster? You have certainly felt the horrifying thrill of this ride when it moves through the track at 60 miles per hour. Some of you must have thought it to be a very dangerous and sworn not to ride it a second time. But actually it is not dangerous as you think. Do you know why? Because Amusement park rides use physics laws to imitate danger, while the rides themselves are typically very safe and so is the roller coaster. The roller coaster has no engine. Once the car is pulled to the top of the first hill at the beginning of the ride, the coaster completes the ride on its own after that. You aren’t being pushed around the track by a motor or pulled by a hitch. The conversion of potential energy to kinetic energy is what drives the roller coaster, and all of the kinetic energy you need for the ride is present once the coaster descends the first hill. Different types of wheels keep the ride smooth and guide the coaster on the track. Friction wheels control lateral motion (movement to either side of the track). A final set of wheels keeps the coaster on the track even if it’s inverted. Compressed air brakes stop the car as the ride ends. So now, go and enjoy the ride to the fullest!
