EPI Ideas?

[Floatzel98]

I've read up on some ideas I can use for my Motion EPI but i haven't found any that i have liked yet. I was just wondering if anyone had any other ideas I might be able to use for my experiment. A lot of my friends are doing projectile motion based experiments but I'd rather not do any like that.

I finished mine a couple of weeks ago. My groups was a lego car, using LEGO NXT that was tied to a trailer with a tension gauge between the two. THe car would tow the trailer up an incline, and we changed the angle of the incline, adn the weight of the trailer. We then got the results, graphed them and compared them to the results using traditional formulae to compare the accuracy. Havent got the result back yet. Not sure how helpful that is, but might spark some ideas.

inclined planes (relationship between angle and time taken for an object to reach the bottom), springs (mass and extensions- verification of Hooke's law), somehow trying to model a collision and measuring initial/final speeds to verify conservation of momentum, lots of possibilities for circular motion (you can model a roller-coaster/loop-the-loop that also lets you use your knowledge of energy concepts, swinging a mass in a horizontal circle, conical pendulums etc)
