How do you calculate force? I know its mass times acceleration but do you use average acceleration or instantaneous acceleration at a certain point in time?
My prob is how do i get the axle into the wood? The other thing is I don't know where to find wheels or how I can substitute something to use instead of wheels... I have the general idea of the car in my head I'm just not sure about the actual building
Sorta except that I still don't know how to attach the axle...and I know the rope would have to be much longer than 5 meters...and I have no clue how to make it go around that many times
I was sort of thinking the same thing except I'm running into the problem of materials. It can go as high as one meter but I don't know how to attach the pulleys so that they spin the wheels (I also don't know what to use for wheels). I was thinking build a base for the car with a tall pole...
[FONT=Century Gothic]Okay, going completely crazy here. I'm in accelerated physics and we just got assigned the gravity car. The way its supposed to work is like this-- a weight is supposed to be dropped from a certain height and its supposed to propel the car forward (GPE converted into KE and...
