I need some ideas for an OEI i have to do soon. I was thinking of getting of the classic drop and push (at the same time) to see the unchanging rate of gravity depite activity on the y axis but i don thave a good camera to map it (which i would like to do).
I was also going to find the best angle for maximum range but half my class is doing that so...
Any ideas?
