well isn't friction supposed to stop motion....so why/how does it help an automobile move??

Think of it like this, if you have a car on ice, there is no friction. The wheels will spin, but the car won't go anywhere. If you have a car on pavement, the wheels spin and the car moves. This is because the friction where the wheel is touching the pavement doesn't move. Instead,the wheel to rotates and the next part of the wheel touches the pavement and 'doesn't move'.
Hope that makes sense. I was never all that good with physics.

Friction is one of the coolest things. When your shoes are too slippery and the surface is to smooth there is little friction so you slide and cant generate forward motion. If your shoes have a gum or soft rubber sole and the surface is a smooth wooden floor( basketball arena floor) your shoes holds to the floor allowing you to use the energy of your muscles to push against the floor to move forward,upward or sideways in more controlled manner. Substitute yourself for the car and the tires as your shoes... Voila! Friction. When your car needs to stop The brakes squeeze together on the Disc Rotor stopping the wheels from rolling. Friction in action. But if the Road is Icy, even though the wheels are not turning the car will still keep moving/sliding. Not enough friction. Hope this helps.

Friction is needed between the tires and the road. If there was no friction, the tires would only spin and the car would not move (think of a car on ice). The same thing is needed when the car turns, if there was no friction, the car would keep moving in a straight line and not actually turn (again, think of a car on ice). Ice effectivly reduces the friction between the road and tires.

Friction helps a car move with traction. Without friction, the tires would spin against the road instead of moving the car forward. The same would be true of stopping.

Well, that's actually a pretty complex question. The friction, in and of itself does not "help" the automobile move. In fact it hinders it. However, due to technology or lack therof, we have to deal with friction as a component of travel currently. The friction makes us burn more fuel to compensate for it's existence. Without it we would have near zero enrgy costs for travel.

Think about what it's like when there's ice on the road...
