Maths & Physics Help
astarmathsandphysics:
I think there are only five types of question they can ask. It shouldn't be too hard to learn them all. Shall I do some specimen answers/solutions? Or you could post some questions here.
saifalan:
Plz dnt mind me asking, wht kind of student r u ?? I mean r u an average or above average. Give us an example of ur avrge percentages. Vectors in O levels arent that hard, heck it aint tht hard in Alevels. May be u tend to memorize maths than understand it, which I used to do. So u cant be better when u do that. Think carefully where u r going wrong.

Why does a car move forward when the friction on the tires is forward and the driving force backwards?

The friction force is ALWAYS against the direction of motion. If the driving force it backwards it does not mean the car is moving nackwards only that the acceleration is backwards.
Pharoah:
But if the acceleration is backwards shouldn't the car move backwards too? I don't understand.. ???
