Title: Physics Extended Practical Investigation
Post by: alx6395 on February 28, 2012, 10:16:25 pm: Hey guys,
I have a Physics EPI (Extended Practical Investigation) coming up and i am so lost as to what i should do for my experiment. The guidelines are that i have to have two independent variables and they must have a non linear relationship.
I would really appreciate it if you guys could give me some ideas, it would really help me

I would also 0.500kgs as my constant mass.

Are you going to change the surfaces so that there would be different types of friction?

A tape measure, I can set the dynamic carts as far as I want to, but definitely somewhere under 100 cm or 1 metre.

Just any sorts tables will do.
