Car has same kinethic energy/traveling north and traveling south. is the momentum in both cases the same?

physicsCar has same kinethic energy/traveling north and traveling south. is the momentum in both cases the same?
Momentum is not the same for each direction as momentum is a vector and must specify a direction. The amount (magnitude) of the momentum is the same, but the direction is different, so the momenta are different in this example.Car has same kinethic energy/traveling north and traveling south. is the momentum in both cases the same?
The momentum is the same in terms of magnitude, assuming both have the same conditions. However, since momentm is a vector, their direcion is different.
