It depends on what you're after. Momentum is the product of mass times velocity. Mass is a scalar quantity, but velocity may be treated as either a scalar or vector. "Vector" means that it has a direction. This matters if you're calculating how billiard balls will interact, but not so much if all you're doing is throwing one.

What are 2 factor does momentum depend on?
By definition p=mv: momentum = mass * velocity (speed if you don't care about direction)
The momentum of an objects is in the same what as its velocity?
In the same direction. Both momentum and velocity are vectors.
Explain how momentum is conserved when a ball bounces against a floor?
The ball's momentum changes in one direction, the momentum of planet Earth in the opposite direction.
Why does momentum have a direction?
Because momentum is mass X velocity. Velocity has direction, otherwise it is speed.
What does change in momentum mean?
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.

How can an object have negative momentum?
momentum is a vector quantity and therefore has direction. all vector quantities can have negative direction
How is direction of acceleration related to direction of momentum?
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.
Is momentum downwards?
Momentum is a vector, the product of a scalar (mass) & a vector (velocity). As such, its direction is whatever direction the velocity vector has.
Momentum has the same direction of what?
Velocity!
Is momentum inversely proportional to velocity?
No, momentum is directly proportional to velocity, and in the same direction..
Why does your body go left when a bus turns right?
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'.
