Anyone have any prac reports on vertical circular motion?

[VCEMan94]

I'm thinking of doing an EPI on vertical circular motion, so if anyone had any sample reports relating to circular motion and swinging something on a string it would be greatly appreciated

or just some advice on what to test and how to get good marks in the discussion/error analysis would also be awesome

thanks

Do you mean a pendulem?

I remember we did a prac where we had a rubber plug set up as a pendulum. As it swung down it hit a hotwheels car on a track which then went down a ramp to fly off into a cup. It was pretty intensive if equating all the separate energies and approximating the distance of the cup from the ramp in order to have the car fly exactly into it. Sadly my reports were burned in a horrible house fire that only consumed my VCE notes before it was quickly put out. Good idea for a prac though!

nah not pendulums

we're swinging a string and mass in a circle
then going to change period, mass, radius etc
to see how it relates to formula
something like that
