PAPEr RRV Project
Materials:
The materials used in building our paper RRV were metal paperclips, a tape measure, the paper RRV template, a box cutting knife, and a phone to record video. The knife was used to cut out the paper template and the paper clips help the RRV together. |
Predict, Observe, Explain (POE):
Control Predict: Observe: it caught air and started spinning/ rotating around 47 inches Explain: -0.5 Predict: Observe: The skinner width made the velocity and acceleration not as fast as the other variables, with the longest flight time as 4 secs. Explain: 0.5 Predict: Observe: Explain: 1.0 Predict: Observe: Explain: 2.0 Predict: Observe: Explain: |

Conclusion:
After running many tests, and looking at the data a conclusion can be made about how changing the bodywith with a paper rrv can change the flight of it. The 4 different changes made to the body with where -0.5 inches, +0.5 inches, +1 inch, and +2 inches Starting with speed and flight time, the fastest of the bunch was +2 inches then +1 inches followed by +0.5 inches and lastly -0.5 inches. The +2 inches RRV hit a speed of 34.9 inches on 2 out of the 3 tests, the average was 33.93 inches per second. The +2 inches RRV also finished 2 out of the 3 trials in 2.75 seconds, and averaged 2.83 seconds. The slowest being -0.5 inches, on one of the trials this RRV took 4 seconds to complete its flight, and averaged 3.41 second flight time. Also on 1 of the trials the RRV speed was 24 inches per second, the -0.5 inches per second average speed came out at 28.33 inches per second. The control test, being a stander RRV hit a top speed of 27.4 inches per second and a time of 3.5 seconds. The control averaged a speed of 26.2 seconds and a time of 3.65 seconds. However there was likely an error on the drop or timing during one of the control test, as the rest of the data will show that the bigger the body the faster the RRV will be and Smaller bodied RRVs will be slower. Changing the bodywith does affect the amount of spins the RRV will do, the control averaged 12 spins compared to the 13.66 the 1 inch RRV averaged. However the lowest spins counted was the 0.5 inches RRV. it averaged a 10.33 spins per drop, that was likely due to it posting a 9 spins on one of the drops. From this data a conclusion can be made that +1 inch is the premium bodywith for spins. A possible reason for the +1 inch RRV getting the most spins is because it had the best spin distance, meaning it spun for the longest distance. The +1 inch RRV spun for on average 81.33 inches out of the 96 total inches the RRV traveled. The -0.5 inches RRV however on spun for 61.33 inches on average out of the 96 total inches. From all of this data a conclusion can be made about bodywith. By making the body with bigger you will get a faster speed, and by making it smaller a slower speed. Also by changing the body with there really is no correlation about how changing the body with changes the amount of spins, except for +1 inch. An engineer could possibly make a theory that +1 inch is the perfect body with for spins.
