Because momentum is mass X velocity.
Velocity has direction, otherwise it is speed.
Momentum is defined as inertia multiplied by velocity. And velocity has a direction. When a object interacts with other objects they collide and change directions.
Momentum is the product of mass x velocity, and velocity has a direction. (In both cases, the direction is simply the direction in which the object is moving.)
In the same direction. Both momentum and velocity are vectors.
The ball's momentum changes in one direction, the momentum of planet Earth in the opposite direction.
It means that the momentum increases, decreases, or simply changes its direction. The latter is because momentum is a vector quantity (that is, the direction is relevant). Momentum is defined as the product of velocity and mass.
momentum is a vector quantity and therefore has direction. all vector quantities can have negative direction
It isn't. The direction of momentum is the same as the direction of the velocity - of the movement. The direction of acceleration, on the other hand, is the same as the direction of the net force that acts on an object - and this force can be in any direction.

Momentum is a vector, the product of a scalar (mass) & a vector (velocity). As such, its direction is whatever direction the velocity vector has.
Velocity!
No, momentum is directly proportional to velocity, and in the same direction..
Momentum. Momentum is mass x velocity. Velocity is speed in a direction. Even if the bus changes direction, you still have momentum in the original direction until some force pushes you in another direction. That takes a moment in a car or bus, so until your momentum is that of the bus, you'll still be going in a slightly different direction, which happens to seem 'outwards'.
The velocity.
