Today, our AP physics class had a lab.
The task was to caclulate the velocity of a projectile gun, then the next day place the gun at an angle, which we measure and calculate the distance away to place a street cone with a hole cut through the top so that the projectile would land directly in the hole. If it did, we would score a 100. If it didn't we would score a 70.
Although we did the calculations correctly (they have been verified), we missed the target. The reason we presume is inaccuracy of the instruments of measurement. We had a wooden meter stick and a plastic protractor, both of which had been used for several years, including summer school. We were very cautious in taking measurements but it proved to be in vain.
I was wondering if anyone knew of any devices worth buying or techniques to improve accuracy of measurement.
If you would, please email me at estoydemoda@gmail.com.
Thank you very much
