7. Remove one of the rulers, placing the other ruler so that it faces the ramp stand directly head-on. Place a marble at the top of the ruler and release it. Note the direction that the marble moves after it collides with the ramp stand (see fig. 4). The marble will rebound directly backward with the same speed of impact. Figure 4. 8. Move the ruler so that it is at an angle with the ramp stand so that the marble will not hit head-on, such as in a sideimpact collision (see fig. 5). Note the direction that the marble moves after it collides. The marble will reflect off the ramp stand with the same speed and angle of impact. 9. Return the marbles to your teacher when you are finished with this activity. Figure 5. Conclusion 1. Describe or illustrate how the marbles moved after they collided head-on in step 3 of the procedure. Is KE conserved Each marble will move the opposite way after collision with the same speed. KE is conserved. 2. The marble that was pushed has more KE, because it is moving faster. After the collision, which marble has more KE The slower marble should move the opposite way with a faster speed having more KE, and the faster one should rebound at a slower speed than its original speed, having less KE. 3. Although the bumper car riders are strapped in and do not fly out of the car, their heads are relatively free to move. Two bumper cars have riders that are the same size and mass, but rider A’s car is moving faster than rider B’s car when the cars collide head-on. a. What will be the resulting motion of each rider’s head after collision (assuming they stay attached to the bodies) The riders have the same initial speed as the cars they are riding. The head of the rider in the faster moving car will lose speed and therefore lose KE when rebounding. The head of the slower rider will recoil with a faster speed and thus gain KE when rebounding. b. What will be the resulting motion of the cars after the collision The faster moving car will lose KE when rebounding and transfer the momentum to the slower car, which will gain KE when rebounding. 4. If the marble sitting still at the bottom of the ramp, in step 5 of the procedure, were twice as massive as the marble rolling down the ramp, how would the resulting movement of marbles be different than what you observed Because it is twice as massive, the target marble will move more slowly than the incident marble. Thus, KE is not conserved. 5. Illustrate or describe the movement of the marbles after the collision that was set up in step 6 of the procedure. Is the KE of the marbles conserved after the collision The marbles will move off in a diagonal line from the original paths and at a slower speed. KE is not conserved. 6. How is the direction of movement following the collision in step 7 different from that in step 8 of the procedure The marble will rebound straight back in step 7, while the marble in step 8 will reflect off the ramp at the same angle that it hit. However, both examples illustrate the law of reflection, which states that the angle of incidence equals the angle of reflection. 104 Amusement Park Physics With a NASA Twist EG–2003–03–010–GRC
Names Marble Run—Part 1—Answer Key Task You will work as a group to build a roller coaster and to diagram the forces of motion and energy transformations that apply to the track. Parameters 1. Use 5.49 meters (18 feet) of copper pipe insulation for the track. 2. Select any type of marble, but only one marble. You will be able to make one switch if you want to change marble type. 3. Avoid putting tape on the surface of the track on which the marble rides. 4. This is not a race, so take time to enjoy it. Date Materials • Three half pieces of copper pipe insulation (gray, spongy); each piece 1.83 meters or 6 feet • Masking tape • One marble • Stopwatch • Meter stick Don't forget to label! Procedure 1. As a group, build a roller coaster that has • An initial hill and one additional hill • A complete loop • A gap where two pieces of track do not touch each other • A run that a marble can roll the entire distance of the track (except at the gap) 2. Time five complete marble runs. 3. Sketch the shape of the coaster below. 4. Label the forces that are present during the marble run (include gravitational, centripetal, and frictional). 5. Label energy transformations in your diagram where the potential energy and kinetic energy increases or decreases.
