positive acceleration helps to increase the velocity for positive direction while negative acceleration resists the motion.

Positive acceleration affects motion because upon acceleration the car has moved very quickly forwards and the driver's body was expecting the same still and constant movement. The driver has moved within the car, by force, and has been pressed back into their seat because if you accelerate then the car continues to travel forwards but at a faster speed than before, sending you back into the seat. Your motion has been affected (you have moved backwards) because of the positive acceleration. It is the reverse with negative acceleration. (the driver's body moves forwards/away from the seat because the body is expecting the same constant movement when in fact the car has stopped and so the body moves forwards as it would if the car did not stop. (does that make sense?) Thankfully we have seatbelts which stop us moving further.

So that is how both positive and negative acceleration affects motion.
