Results:
(I’m so sorry I can’t rotate the pictures so you’re gonna have to rotate your head)
Discussion:
What are the 4 main forces acting on your wind racer –
- Non-contact force, Thrust, Friction, Gravity.
- What forces made the racer go faster / slower | Slower- friction | Faster – Thrust
- What would make some wind racers go faster / slower? – Lesser friction
- What is speed- motion travelling either faster or slower
Although we did not win the wind race, we did win for which windracer was more appealing to the eye.
We reached our goal (aim)
Conclusion: The wind racer’s purpose wasn’t fulfilled although I think we did a good job decorating the windracer. I wasn’t present during this activity. Although I’ve heard from a associate that the windracer that we built did not make it well. The wind had blown it and it went backwards.
