Roller Coaster Design using Inertia

Keeping You in Your Seat

  • Your inertia wants you to stay in a straight line but the roller coaster pushes you up into a loop
  • When you begin to enter the loop, your acceleration moves you along with the coaster and pushes you out of you seat, while your inertia wants to keep you in a straight line, therefore it pushes you down back into your seat as you go around the loop

Changing the Design of the Loop

  • Before 1901, The roller coaster loops were designed as perfect circular loops
  • This design had the same angle of trank the entire way through, with made it harder for the ride to accelerate
  • A large amount of force was needed to get the car all the way up to the top of the loop because of the other forces acting upon it ( gravity, inertia, etc.)
  • This amount of force caused great discomfort as well as several neck injuries
  • The design was then changed to the modern day shape in 1901 by Edwin Prescott who designed the Loop-the-Loop on Coney Island
  • The new revised design made the loop into a teardrop shape
  • The angle at the top of the loop was now sharper than the angle of the track at the sides
  • This way, the the car would have an adequate acceleration at the top of the loop and reduced acceleration forces on the side
  • This gives them enough force to run the ride but not too much that the ride would be dangerous
