Final Report for catapult project
Subject:
i. Abstract The purpose of this experiment was to test how the angle of the catapult and the tension of the string can affect the range. When the table of angle values was plotted in relation to the range, the maximum range on the graph was at an angle of 45 degrees. The results showed that the optimum angle of the catapult for the greatest range was 45 degrees. When tension was plotted against the range, there was a linear relationship. This indicates that the greater the tension of the string, the greater the range. ii. Introduction

newton 1) objects will stay at rest and stay in motion until acted upon by an outside force
2) acceleration depends on mass and net force
3) object applies a force on another object, second object applies a force of equal strenght
