Rocket Launch Presentation

By Ethan Smith and Connor Bryson

Claim

Q: What features will allow a rocket to stay in the air the longest?

A: The curved fins and the extended nosecone will stay in the air the longest.


(throughout, when we say 'their' and 'it's', we're referring to ourselves)

Evidence

This rocket utilized curved fins and an extended, pointed nosecone to stay in the air the longest. While this rocket was definitely not the best, it's features worked as they were intended to. The features that work better than this rocket's seemed to be using a functional parachute and different fins. To keep the rockets up, everybody should have added a nosecone and fins. These features would at least hold it in the air longer.

Reasoning

The reason that these features were best for this rocket was that its designers wanted a spiral flight pattern, which they thought would take the rocket higher. While the curved fins did cause the rocket to spin VERY well, it didn't make the rocket fly any higher. They also had a long, more pointed nosecone, so that the rocket could have less drag and therefore, accelerate quickly. This feature did work as intended. Their rocket flew very high very fast. The only issue was that they did not include a parachute attachment to the rocket, so it also came down very fast. According to Newton's Third Law of motion, for every action, there is an equal and opposite reaction. When the rocket was splitting the air, the air was being forced away and down. When the rocket was forcing its way upward, gravity was fighting it, and eventually forced it back down. Their rocket was sadly demolished on impact. But, the features they used worked as intended.
