Nose Cone Designs Lab Report

Good Essays
The experiment conducted was to observe how changing factors, including nose cone designs and volume of water would affect a water rockets maximum vertical displacement and the forces involved. It was hypothesised that the round cone would travel a greater distance in comparison to the square and pointed cones. Another assumption that was made was the water rocket with the 750 ml volume of water would be the most effective and would travel the greatest distance in comparison to the 500ml and 1000ml volumes of water. As seen from the results collected, it suggests that these hypotheses were supported and matched the expected outcomes with experimental errors and uncertainties.

Table 1 illustrates the collected measurements for max height reached(m), max velocity reached(m/s), acceleration (m/s^2) and drag subjected on the water rocket with differing nose cone designs. These results show the round cone had an acceleration of 25.22 m/s^2, consequently, it had the least amount of drag of 19.54N. In comparison the square cone had the greatest acceleration of 36.52 m/s^2, thus, it had the highest drag of

All six motions are a parabolic motion. The r^2 values suggest this as they are close to 1. This is to be expected as water rockets use the theory of projectile motion. An object that is projected will continue to be in motion by its own inertia and is influenced by the downward force of gravity(Berkeley Engineering, unknown). Rockets apply this theory as once they are propelled by the initial thrust it will continue to move in an upward motion until the direct force is stopped, then it will follow a path identical to that of a projectile motion, in which the gravity acts to return the rocket back to the ground. The motion of the rocket can be described using a simple quadratic function (polynomial of 2
