Looking to do an EE in Physics (mechanics). Help / Suggestion please?!?

[Shroosh]

Hey everyone, I'm new here and I'd like a little help before I start my Extended Essay. I'd like to do it in Physics because I want to be an engineer (still not sure but probably mechanical or aeronautical/aerospace) and so I think it would be pretty pointless to do it in another subject.

I had one idea where I could investigate the stopping distance of an RC car on different terrain surfaces. My mentor made it clear that the data collected needs to be quantitative and so I changed the it to the effect of friction on stopping distances. I'm still unsure about this because it might be too simple or a standard investigation.

I'd like some help and suggestions about this please.

Thanks!

Choosing an EE subject is more of an interest thing. But anyway, stopping distance sounds fine to me (I'm not sure, so don't take my word for it), although I can't really think of a way of you measuring frictional coefficient.

I did effect of friction on stopping distance for my Group 4, my results weren't all that accurate but that's probably because we didn't have a lot of time to perfect it.

If you do a science EE make sure you collect all your data early!

Just to be clear, is it better to have very accurate or not very accurate results in the EE? I've found that in Physics Internal Assessments there is generally more to say about an experiment - in terms of uncertainty and what not - if it is not incredibly accurate.
