Flight Deck, Vortex, The Demon, Invertigo, Orbit, Delirium, HMB Endeavor. 3. Anything that involves circular motion is a velocity dependant force, and that would include merry-go-rounds and loops in roller coasters. Gravity is not a velocity dependant force because gravitational force is the same no matter where you are on Earth. 4. Amusement park rides should be designed for acceleration, because acceleration depends on speed in many cases. 5. A roller coaster has to gain gravitational potential energy at its first climb and some of its potential energy is converted to kinetic energy. Similarly, a pendulum has no kinetic energy and only potential energy at its highest position. 6. Yes, at the top of every motorized incline on any intense roller coaster. 7. Yes, at the bottom of the motorized incline, potential energy can be relatively zero and there can be kinetic energy. 8. Yes, I have neither kinetic energy nor potential energy when I stand on the ground motionless. 9. Yes, when the roller coaster comes to a stop at the end of the ride. Yes, when the roller coaster is at the top of a loop. 10. Drop Zone, Invertigo, all the major roller coasters at the top of the motorized incline; Extreme Skyflyer 11. Carousel Columbia. Yes, the Eagles Flight is an example. 12. My organs feel acceleration. The human body is an accelerometer because we feel the drop when we make the drop after the motorized incline on any major rollercoaster yet we feel nothing when we are cruising at 500 mph in a jet. 13. (1) Roller coasters at the loading station stay at rest because there is no net force acting on it. (2) The air hockey puck at the arcade stays in motion on an almost frictionless table. (3) The go carts are stationary when they are parked because there is no net force acting on it. (4) The bumper cars move at a constant velocity when there are no collisions, because the car’s motor cancels out with the friction force. 1. I feel heavier on The Demon, as it is entering a loop. 2. I feel lighter than normal on The Demon, as it is exiting a loop. 3. Drop Zone, as the riders are dropped from high above. 4. As I enter an incline after the first hill on The Grizzly. 5. Kinetic energy is converted to heat as The Demon comes to a stop at the end of the ride. 6. On the Flight Deck, the longitudinal g-force is less than 1 g when the track curves downward. 7. On the Flight Deck, the longitudinal g-force is more than 1 g when the track curves upward. 8. On the Flight Deck, the longitudinal g-force is opposite when the car is coming to a stop. 9. On the Flight Deck, the lateral g-force is significant on the twirls. 10. Centripetal force is horizontal everywhere on the Carousel Columbia. 11. Centripetal force is vertically upward during the peak of the ride nearest the ground. 12. At the loading station of The Grizzly, pads on the track stop the car. 13. A. When The Grizzly comes to a stop at the loading station. B. At a loop on the Invertigo. C.
