I made a 14-centimetre long paper rocket. Then I shaped a 2-cm nose cone and carried out 5 flights. After that I changed the length of the nose cone into 4 cm and carried out another 5 trials.
This is how my rocket looked like before shaping the nose cone:
These are the results:
NOSE CONE | TRIAL 1 | TRIAL 2 | TRIAL 3 | TRIAL 4 | TRIAL 5 | AVARAGE |
2 cm | 208 cm | 235 cm | 200 cm | 208 cm | 201 cm | 210,4 cm |
4 cm | 188 cm | 160 cm | 174 cm | 200 cm | 150 cm | 174,4 cm |
According to these results, the flight distance depends inverse proportionally on the lenght of nose cone. The longer is nose, the shortest is flight. Unfortunately, the exact determination of this dependance requires equal rocket propulsion during each take-off. Even though I tried to, I’m not able to say that all of my blows had the same strength. Since scientific experients require precision and measuring all of the agents, the results of my experiment can be read only as a general rule.
And these are our other strew rockets:
