I know graphs such as position-time, velocity-time graphs are things that have to be known. How about Force-Time graphs?
I have never come across one on a test or even in the book. Can anyone just tell me the fundamentals of this graph type.
Cheers in Advance.

The area under a F-t graph is the change in momentum (ie impulse). There's not much else to it.

How about when a question asks you a car goes to the right with a force towards the left? What direction would the graph go towards?
-
Not sure, I've only used them for collisions

If you take right as positive then the graph will be negative. The impulse is the "signed area" so it would be negative of the actual area (if you know integration then this is pretty much it)

hey onur... u know for the chekpoints h/w we got.. i dont have the book .. so hw the hell am i meant to do it?
??

Easy, don't.

yeah so basically just define your vectors first and the rest follows
