Pintian Zhang Zhirong Bi Namaneet Galgaii Lynn Ri Experiment Purpose: Test the catapult to find out how changes in factors affect the range. Factors that can affect the range: Angle which the catapult is aiming Tension of the string Angle test: Change the angle of the point where bolt shoots and ground, shoot the bolt, then measure the range. Other factor, such as the force applied and the height of the catapult needs to be kept constant. Shoot the bolt twice each angle to avoid percent error. angle Trial 1 (cm) Trial 2 (cm) Trial 3 (cm) average range (cm) 10 55 54 54 54.33 20 57 59 57 57.67 30 57 59 58 58 45 62 67 65 64.67 50 58 60 60 59.3 60 56 54 55 55 70 56 53 54 54 80 50 46 48 48 Graph the average data and determine any relationship between angle and range.

Unformatted text preview: Come up with an equation of line of best fit, if possible. Tension test: Measure the range for each trial below. Force can be measured by attaching the end of the string to spring scale before shooting. force Trial 1 (cm) Trial 2 (cm) Trial 3 (cm) average range (cm) 10 5 6 6 5.67 20 20 18 17 18.3 30 23 23 24 23.3 40 30 27 25 27.3 50 30 33 31 31.3 Graph the average result and derive any relationship between force of tension on the string and the range.
