4. Rocket propulsion as used for space travel.
5. Atmospheric studies: how does temperature and pressure affect performance?
6. Planetary differences: how does
same rocket perform on different planets in our solar system.
7. Dynamics and harmonic motion with damping.
8. Engineering - how parts fit together.
9. Newton's Laws of motion.
10. Artistic expression – because every student can design a different looking rocket, and change colors of
components to further increase
rocket's uniqueness.
11. Explaining distance, velocity, and acceleration.
12. Material properties, like density and volume.
13. The importance of weight and balance (CG position) when designing rockets.
14. Explaining that Work = Force X Distance.
15. Explaining
concepts of Kinetic and Potential Energy.
16. Showing free-fall, and terminal velocity.
17. The importance of units and unit conversion.
18. The importance of following directions.
19. Exporting data and using spreadsheet programs to perform data reduction and manipulation
20. To show why multi-stage and cluster motor rockets are used in real rockets.
21. Concept of stored chemical energy (in
rocket propellant) and how it is converted to mechanical energy.
22. Concept of efficiency - getting
most performance from
least exertion of energy. Can be explained by
different types of propellant formulations.
23. Showing
concept of momentum and how it affects
optimum mass of
rocket.
24. Finding
optimal launch angle for breezy conditions.
25. Optimal launch angle for distance (ballistic curves), and how it varies with
thrust curve of
motor.
26. Show how
distribution of mass affects
dynamic stability of
rocket.
27. Demonstrating
concept of "Numeric Precision" --
more iterations performed,
better
accuracy.
28. Show how different shaped components affects
static stability of
rocket.
29. Compare
thrust curves of different motors. This can show how different geometries (hole size, location, dimensions) affect
thrust produced by
rocket.
30. Concept of "Impulse:" which is a thrust force multiplied by
time duration that thrust is created. The higher
impulse,
more power
motor has.
As you can see,
RockSim software is a versatile tool. You'll save hundreds of dollars because it can be used in a variety of ways.
