Hypothesis and variables

Solid Motor Rocket Propulsion

Abstract

What does it take to launch a satellite to explore Mars, or a mission to the moon? This project has several possible variations for exploring the physics of rockets. This is rocket science!

Objective

The objective of this project is to measure changes in a rocket's performance based on differences in the rocket's motor.
