Model No. ME-9812 Roller Coaster Introduction The ME-9812 PASCO Roller Coaster has loops and hills for studying conservation of energy and centripetal acceleration, a straight track for collisions, and a brachistochrone to demonstrate the path of least time. Track Assembly 1. Plugging in the Hole Inserts (one-time installation): To prepare the ME-9812 Roller Coaster for first use, the hole inserts must be plugged into the holes.
Roller Coaster Model No. ME-9812 2. Using Support Feet with the Support Panels There are many different track configurations possible (see pages 1220 for examples). Some use two support panels and others use three support panels. The support panels can be used in different orientations, rotated 90 degrees from the usual orientation. The panels are supported in the vertical position by placing them end-to-end in the slots of the black support feet.
Model No. ME-9812 Roller Coaster Track Configurations are shown in the Suggested Activities section. If desired, shorter sections of track can be spliced together using a track coupler, which is a metal strip that slides into the slot on the underside of the track. Slide the coupler halfway into the end of each track section to join the two sections together. 4. Attaching Photogates to the Track There are special pegs with threaded rods on one end that are used to mount photogates.
Roller Coaster Model No. ME-9812 • It can be used as a catcher on the Rotating Platform (ME-8951) to perform a conservation of angular momentum experiment: The car goes off the end of the track, into the catcher, and the platform rotates. a) To attach catcher to the track, squeeze the spring metal clip and catcher rubber band insert the clip into the slot on the bottom of the track, then release the clip (See Figure 5).
Model No. ME-9812 Roller Coaster To make hills, lay the track over a stack of books. The track can be suspended in a configuration of your own design using any rod stands with half-inch diameter rods to which the track can be clamped. CAR ASSEMBLY OPTIONS 1. Wheel Labels Labels which simulate the look of a wheel are supplied for the user to apply to the flat circles on the car body. 2.
Roller Coaster Model No. ME-9812 to help keep them from slipping off the car. The bumpers are also used to couple two or three cars together for a roller coaster train. To accomplish this, put rubber bands on the bumpers to make elastic V-slot bumpers. Then place the pointed front bumper of Figure 8: V-slot on the bumper the trailing car over the rubber band of the car in front of it, letting it fit loosely into the "V" slot of the leading car (see Figure 11). 3.
Model No. ME-9812 Roller Coaster 4. Adding Ballast Mass and Additional Masses The ballast mass fits underneath ballast mass the car (Figure 10) and is attached using an M5 screw (supplied with the rollercoaster). Additional cylindrical masses can be placed on top of the car in the mass tray.
Roller Coaster Model No. ME-9812 SUGGESTED EXPERIMENTS (WITH CONFIGURATIONS) 1. Loop (One Car) There are two basic configurations for the loop (see Configurations 1a and 1b): Both begin on the left using the highest track path, but there are two ways to end the track on the right. One configuration is steep on one side and shallow on the other to emphasize that the car goes to the same height on each side (ignoring friction).
Model No. ME-9812 Roller Coaster 2. Cup of Water Over Loop Place a cup of water in the mass tray of the car and let the car go around the loop. Will the water stay in the cup as the car goes over the loop? Put a catcher at the end of the track so the car will be caught instead of going back through the loop. 3. Three-Car Coaster When using three cars linked together as a roller coaster, begin on the left on the step that is second from the top. (See Configuration 3.
Roller Coaster Model No. ME-9812 5. Conservation of Energy (Hills) If the car is released from rest from the top of the lowest left step (the second peg from the bottom is the first step; see Configuration 5), the car will make it over the hill without flying off the hill. If the car is released from higher up on the right side, the car will fly off the hill.
Model No. ME-9812 Roller Coaster 7. Brachistochrone vs. Straight Track The shortest distance between two points is a straight line. Which car will travel from Point A to Point B (Configuration 7) in the least time: the car on the curved track or the car on the straight track? A B Configuration 7: Brachistochrone vs. Straight Track 8. Brachistochrone vs. Brachistochrone at Different Start Positions Put two tracks side by side along the Brachistochrone path (See Configuration 8).
Roller Coaster Model No. ME-9812 9. Acceleration Down Different Inclined Tracks In Configuration 9, the three inclines on the left board are straight for a short distance. Measure the acceleration of the car on each of these inclines. The acceleration can be measured using two photogates on successive pegs and a Smart Timer (ME-8930) set on “Acceleration: Two Gate” mode. Measure the angles of the inclines and calculate the theoretical accelerations.
Model No. ME-9812 Roller Coaster 12. Projectile Car Off End of Track (3 different steps) Set up the track as shown in Configuration 12. Allow the car to go off the end of the track onto the floor in projectile motion. From which of the three steps will the car go furthest? Place some sort of cushion on the floor to soften the impact. Configuration 12: Projectile Car off End of Track 13.
Roller Coaster Model No. ME-9812 14. Oscillations in a Well Set up the track as shown in Configuration 14a or 14b. Time the period of the oscillations in the valley. Depending on initial speed and position, the car will be trapped in different potential wells. Configuration 14a: Oscillations in a Well Configuration 14b: Potential Wells 15.
Model No. ME-9812 Roller Coaster 16. Position, Velocity, Acceleration Set up the track as shown in Configuration 16. Ask students to predict the shape of the position, velocity, and acceleration versus time graphs for the motion of the car as it travels down the straight slope, then on the level, and then down another straight slope. Then show students the motion of the car and make measurements using photogates and a Smart Timer to check their predictions.
Roller Coaster Model No. ME-9812 18. High Road and Low Road Set up two tracks side-by-side (Configuration 18) and race two cars. Which car will win? What are the final speeds of the cars at the end of the track when they are back together? It is interesting to hang a cloth on the pegs of the high road to hide the low road. The car on the low road disappears behind the cloth and reappears on the other side in a surprisingly short time. Configuration 18: High Road vs.
