Yes, thankyou. Sorry, i hadn't thought about the question properly before i asked, I've really just been trying to see if my idea is feasible to use for my coursework. It would be great if you could answer though.

If instead i was to ask what the error margin would be if i was going to drop the spheres from 2 metres, would be be able to oblige me with an answer? :smile: My experiment is not going to be hugely accurate anyway, as the density of the spheres won't be even, as they have to contain a magnet...

Thankyou. I think it might be best if i did an initial experiment from a large height so it has time to reach terminal velocity, and working out the drag coefficient for different spheres. Would the drag coefficients stay constant, so i can use them to work out the drag at velocitys below...

I am planning an experiment for my coursework in which i am dropping spheres of different mass and calculating their drag. They will be of different sizes, but are made of plastercine so are relatively light. I would guess the heaviest would weigh no more than 20 grams. Does anybody know...
