The Effect of Bow Shape on the Average Velocity of a Boat
The objective of our experiment was to determine which shape of the bow of a boat would give an output of the greatest average velocity. There were three different bow shapes tested: round, triangular, and flat. A bow piece was attached to a battery-powered boat which was then set into a tube of water. The boat was turned on and run through two photogates that were set half a meter apart. The photogates measured the initial and final velocity of the boat. The two velocities were added together and divided by two in order to obtain the trials average velocity. The average velocities of the round, triangular and flat bow pieces were then analyzed with a one-way analysis of variance test. The test was conducted and it was determined that the three bow shapes did not have significantly different average velocities.
