Extract of sample "Establishing the Relationship between Projectile Horizontal Distance and Angle of Projection"

The procedure was first followed for the homemade catapult with an angle range of between 00 and 1000 and single trials. A penny of mass 3.06g and 2.21g were used for the homemade catapult and launcher respectively. The maximum distance was realized at 600 for both the catapult (62 cm) and launcher (72.6 cm). Uncertainties were 5 cm for distance and 50 for angle.

Theoretically, 450 should be the angle for maximum distance while the distance should be zero for projections at an angle of 900. This was however not the case because the maximum distance was realized at 600. The recorded distance at this angle, however, corresponded with the theoretical value of distance at 450. The distance was also not zero at 900 but was smallest at this angle. Even though the experimental results were different from theoretical expectations, they converged towards the expectations. Human error such as an inaccurate measure of angles could have caused this.

Projectile Motion

In the second part, the experiment investigates ratio of the average velocity versus muzzle velocity that is, if the horizontal velocity is constant during the flight, then it should be equal to or very close to the muzzle velocity and this is achieved by setting the gun at an angle of elevation of 35 degrees.... There will be no change provided the initial horizontal velocity and the angle of elevation is kept constantWork citedKnudson, Duane V.... One possible cause of the uncertainties is the inaccurate timing from the time projection and the exact time of landing an error that can be attributed to the inaccuracy of the observer causing random error....
