So we need to make a practical report and I'm not sure how to do it. I've learnt the basics like lift equals weight and thrust equals drag.. and then the teacher made a model wind tunnel in class, we then got air speed(km/h) and its mass(g) etc. for it then we had to convert them to life and speed (ms-1) which i'm not too sure how to do and then plot them on a graph... Checklist: Now the teacher wants us to make a report.. so for the Aim should i write that we want to find out the air speed and the mass? For background theory should I write about how it was found out?? For Apparatus just the things we used.. For Method: how it was used? .. For data: just the numbers we got... Analysis?? conclusion? I don't know what we were trying to achieve by doing this??... Need help on how to do this and more information for a wind tunnel (investigation to flight (airfoil...)) practical report Thanks.
