Exp. Control (1 Viewer)

[khorne]

I have to write up a prac for physics, about projectile motion in relation to bottle rockets...The basic gist is adjusting the ratio of water:air in the rockets to find max range/height/speed etc.

However, I'm not quite sure if this experiment has a control? I could compare it to, say 0% water: 100% air, and show that the rocket flies without water, albeit badly, thereby showing the amount of water influences the distance travelled...

Could anyone comment on this? This that control appropriate, or would it be best to just leave the control out.

two controls: One with completely water, one with completely air imo

+1

Thanks, repped you both

Double post to bump thread:

Additionally, do you include controls when graphing the results?

Thanks again

When I read the name of the thread.....it brought back memories of Pokemon.

One final question.

I have the results (of three tests, averaged) for the longest range. Would it be fitting if I compared these actual results, to the results which the curve of best fit indicates, or do I just use the actual results?

 

[khorne]

I've done this, but I am not sure if it is fitting to compare the two, given that one is actual data, the other is just "averaged" or interpolated data.

I assumed so...Well, thank you very much
