#PROJECTILE LAUNCHER HOW TO#
The derived formula produced a reasonable calculation, but some sources of error must have occurred, resulting in the slightly faster than expected initial velocity of 5.8m/s. Buy Student Projectile Launcher, SB49115 at Nasco. How to unlock the Projectile Launcher achievement. The results of this experiment support the hypothesis because after the horizontal and vertical displacement were measured, the initial velocity of the dart could be determined because the angle at which the dart was launched was also known. Another experiment could be investigating the acceleration of a dart from a projectile launcher at different angles as well. This could determine how much, if it all, the velocity changes with a different angle from the projectile. If all other variables remained the same except for the angle, the new calculated initial velocity could be compared with the calculation made in this experiment. Projectile options are only limited by your creativity and local laws, many customers are 3D printing projectiles making the impossible, possible. If the angle was not exact each time, then the distance traveled would have differed slightly, affecting the initial velocity as well.Īdditional research that this experiment could have investigated could include the calculation of the initial velocity of a dart at different angles. This unique metal launcher has multiple settings, so launch speed and angles may vary.VWR offers a complete catalog of instruments and tools useful for. Permitted Materials The mechanisms which move the launcher and propel the projectile must consist of elastic material such as springs, rubber bands, bungee cord, etc. A final source of error is the possibility that the projectile launcher could not have been at exactly 45 degrees. Projectile Launcher Objective To build a device that will move forward and launch a projectile (pencil). This friction could have changed the power of the dart and altered the initial velocity of each trial. Another source of error during this experiment was the friction created with the elastic bands in the projectile launcher.
Therefore, the second or third bounce could have been mistaken for the first bounce instead which would have altered the data. Some of these sources of errors could include not precisely measuring the horizontal distance with the slow motion camera because the dart bounced a few times on the ground. Projectile Launcher The Projectile Launcher Immersion Experience demonstrates how projectile motion relates to carnival games, sports and other parts of life. Therefore, some errors must have occurred during the lab. There are no obvious out liars in the data collected, which makes the average horizontal distance calculated seem accurate. It does not seem realistic that the dart could have traveled yet almost another two meters in one second. This seems to be faster than anticipated since the average distanced the dart traveled was about 4m. The initial velocity that was calculated after using the derived equation was 5.8 m/s. Student teams each construct a desktop launcher from a swing-arm protractor and then experiment with launch angles, launch mechanism, and types of projectiles.
