My group and I began to understanding how to apply average velocity to creating a rocket.
Day Three was about understanding the importance of launching the rocket at different angles. What I noticed was that the smaller the angle, the farther the plane will go.
This day was about how the cone's mass affects the straw rockets. My hypothesis was "the larger amount of mass of the cone, the farther it will go". I am incorrect.
I made three cones with different masses. Rocket A's nose had a mass of 3.1 grams and traveled an average distance of 1.05 meters. Rocket B's nose had a mass of 4.6 grams and went an average of .76 meters. Rocket C's nose had a mass of 5.2 grams, but went a distance of .94 meters. My conclusion is that the less mass, the farther it goes. I created two straw rockets. Rocket A is 8 centimeters, and Rocket B is 18 centimeters. My hypothesis was "that if it is too long, it won't go as far compared to using a shorter rocket". The hypothesis is incorrect because Rocket B went farther by an average of .39 centimeters.
