Smile help with reasearch

hi um im doin an experiment about what surfaces effect how far a toy car can go i plan to use an incline plane to make sure speed in the experiment will be controlled and i also plan to use different types of surfaces (carpet,wood marble tile etc.) my project will inclede a display board and a report my teachers says i have to do backround reasearch i really dont know where to look PLEZ help and feel free to post thanx

Default Friction

Do some research on friction.

Yes, friction is one point.

Another one is acceleration (in accordance with friction), and therefore, the rate of gravity depending on the incline and slope of the incline.

Warning: be careful in measuring the speed of the car. It doesn't have a constant velocity (always gaining speed). I think it'll be more safe to measure it in terms of acceleration. Also, try to be as exact as possible. Unless you make a really long incline, it'll be hard to be exact when the cars pass by the incline with a difference of half a sec, but half a sec is all the more important to the calculations.

Also, find some practical applications for this in real life. For example, what should roads be made of? (keep in mind that a slippery road isn't better than a road with so much friction)

Good luck!

Wink a help

i am also a student so i experience those kind of things
you can research friction on the internet in google.com or in wikipedia.com
orse in the encyclopedia.

good luck!
