You are in Six Flags over Texas waiting in line to try Batman the Ride roller coaster.
You boarded the roller coaster and now you're barreling down the track at 60 miles per hour, taking hairpin turns and completing death-defying loops.
Your heart is in your throat and your stomach is somewhere near your shoes! You are having so much fun!
Then you suddenly remember that the laws of PHYSICS are behind all the rides in the amusement park!
You've learned in class that the coaster has no engine. The car is pulled to the top of the first hill at the beginning of the ride, but after that, the coaster must complete the ride on its own. You aren't being propelled 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.
In this PhysicsQuest you will learn the principles of conservation of energy that allow you to enjoy fun and safe roller coaster rides.
You will be given a series of questions and various links to Internet sites that will help you answer the questions.
By the end of this PhysicsQuest you will have a better understanding of the factors that have an effect on the total mechanical energy of an object.
Take a look at the animation depicting cars at three different speeds. You can observe that the red car is traveling twice as fast as the green car and that the blue car's speed is three times faster than the green car's speed.
12. What conclusion can be drawn regarding the stopping
distance and the speed of the car? Explain your answer
