    how will newton's law of inertia relate to a person's motion while undertaking a journey in a vehicle?

    Relate? Relate in what way? It will still be applicable, if that's your question. Otherwise, I smell a school assignment? But I have a cold, sorta', so my sense of smell is a little screwed up. :P

    Agreed. Sounds like 11'th hour to me.

    its sort of a assignment, by relate i mean, how does inertia affect the person when he's in a vehicle? e.g. car suddenly stops, the person is thrown forward.

    I think you just answered your own question.

    The person is not literally thrown forward. It seems that way because you have chosen the car as your frame of reference but it is not an inertial frame of reference since it is decelerating. The person tends to move uniformly straight forward as Newton's first law states.

    Also, when you go around a curve it seems that you are thrown to the outside of the curve. Again, this is because the car is not an inertial frame of reference but is accelerating toward the center of the curve while your inertia tends to make you go straight.
