  1. The GRAVITY force between your coaster and the earth pulls you down the roller coaster.
     
  2. The greater a coaster’s WEIGHT the stronger the tracks must be to support it.
     
  3. You increase a coaster’s MASS by adding more passengers.
     
  4. A roller coaster peak is shaped in a curve called a PARABOLA so that you will feel like you are falling freely as you go over the top of the hill.
     
  5. Roller coaster hills are shaped so that you will feel almost WEIGHTLESS as you ride over them.
     
  6. You gain enough MOMENTUM falling down a roller coaster hill to keep you going all the way to the top of the next hill.
     
  7. You feel ACCELERATION as you gain speed rolling down a roller coaster hill.
     
  8. You feel DECELERATION as you lose speed climbing a roller coaster hill.
     
  9. As your speed increases going down a roller coaster hill, you gain KINETIC ENERGY.
     
  10. Your coaster has the most POTENTIAL ENERGY when it is at the highest point.
     
  11. You feel a FORCE on you back as the coaster seat pushes against you.
     
  12. Your body’s INERTIA causes you to be slung forward when you stop suddenly at the end of a roller coaster ride.
     
  13. Roller coaster tracks are tilted inward to give CENTRIPETAL FORCE which pushes the coaster toward the center of the curve.
     
  14. The rubbing between coaster wheels and the track causes a FRICTION force which slows the coaster down.
     
  15. Your VELOCITY increases as you roll down a roller coaster hill.
