Raman Baig SPH3U Post Lab Observations and Data It was observed during the lab, that the horizontal range for the projectile increased when it was launched at an angle compared to when it was launched horizontally (at a 90-degree angle). This resulted in a larger average horizontal range for the projectile launched at an angle, compared to when it was launched horizontally. This made sense, as launching it at an angle meant that the projectile would have to cover more ground, as it goes up, then comes back down, all the while moving horizontally. Sources Of Error The first source of error was a system error, in which the gun and dart both were not perfect. Every gun and dart had something that would hinder its performance and consistency. For the dart used, it was bent, and no other dart was any better. For the gun, it was finnicky, as it was prone to breaking and firing without being triggered. This gave some difference in each trial such as earlier time of launch due to the misfiring gun, or bit of a different trajectory due to the bend in the dart that could not be controlled. The second source of error was a human error, as it was almost impossible to make sure that the gun would stay at the same angle throughout the second part of the experiment. This made the projectile’s trajectory differ from each trial ever so slightly. This was a factor that was impossible to perfect. The third source of error was a human error, in which the projectile would land, and bounce off from the floor, leaving the spot where they landed. This made it difficult to measure the range of the projectile, as someone had to always get to where the projectile landed before it bounced off.
