Our EPI is coming up sometime soon, and I thought i was lucky to get in quick and reserve the topic which concerns the horizontal distance travelled of an object when it is launched at different angles to the horizontal.
Of course, you would measure the distance at every angry (with perhaps intervals of 5 degrees) and would come to the conclusion that 45 degress results in the furthest horizontal distance. Now thinking about it, it seems a little too simple for something in year 12 Physics. If i just produce a prac like this, then I think i'm going to be in a bit of trouble (in terms of not getting a good mark). I'm pretty sure our teacher wants us to do a Prac. where we identify a relationship between two things or atleast show that through our working out we can establish some sort of relationship, ie - being able to establish the spring constant K of a spring, if you get what i mean.
Basically, with the measuring the distance travelled at different angles, there isn't really much of a forumla to use or to be able to link anything together - all that i will find is that at 45 degrees the distance is the most.
Does anyone have some sort of topics to do, or have any ideas on something else i could do which doesn't neccessarily have to be very hard, but has some more thought behind it , that would allow me to come up with some sort of findings other than just stating that "at 45 degrees the horizontal distance travelled is the greatest".
Thanks for replies
Wow, that does sound like a pretty interesting topic. If you could post some more info that would be a great help mate!!
I just want to ensure whatever i do does have the ability to be researched extensively, and it seems that with the balloons there is plenty of room for research and as you said, if you can find a relationship between the circumference etc and the terminal velocity then thats almost all i would need i think, to satisfy my teachers requirements for a high mark.
Ill wait for some additional info, thanks a lot !
whats your email address?

Will PM you my email address now mate, thanks a lot. Ill ask my teacher tomorrow if we are allowed to do this, as i'm not sure if this is what he meant as projectile motion.
Ey fellas, buttin in an a week or 2 late but iv got my EPI aswell this week an dan ya prac sounds dam good so was wonderin if ya could send it to me too? would be a big help man, cheers
hey guys i am in the same boat as you and i was wondering if Dan could you send me you prac to as the one i was going to do was to complicated for the time that i have
talk to kryziek about it
i dont have time to explain it all 3 times
