=== === Since momentum is a vector and not a scalar quantity, to have the same momentum, they must have the same direction. Remember, vectors have magnitude and direction. Speed is the magnitude part of velocity. Since momentum is the product of mass (a scalar) and velocity (a vector) if two objects are moving in different directions, even if they have the same mass and speed, their momentums are different.

0First of all ... I think you're talking about either the magnitude of the momentum, or the magnitudeof the velocity, not the magnitude of the objects.Now ... you're obviously skating around the subject of vectors here, recognizing that both thevelocity and the momentum are vector quantities.If, as you say, the two objects have " ... the same momentum ... ", then you're saying that theirmomentum vectors are equal. If so, then you'd have to say that yes, since the momentum vectorsare equal, the momentum vectors and the velocity vectors must all have the same direction.But if the two momenta only have equal magnitudes, then they ... and the velocities ... can be inany two directions, not necessarily related.

It is due to the momentum of the two bodies.

The momentum product can be the same with different velocities; m1V=m2rV thus m1/m2=r ratio with V1=rV1.

Yes. If the force of momentum is equal in both directions, the momentum will cancel. This can occur if two objects with equal momentum traveling in different directions collide.

momentum is mass x velocity, so if they have the same momentum but velocity is different then mass is also different

Velocity is a vector; to specify velocity, you indicate a speed (a magnitude), and a direction. If two objects move in different directions, their velocities will be different, even if their speeds are the same.Velocity is a vector; to specify velocity, you indicate a speed (a magnitude), and a direction.

Because momentum is equal to mass times velocity, so if they have different velocity the momentum will be equal if the masses are right. Momentum is also equal to force times time.

An object at rest. Actually that's the only possible example for a single object. For two objects, you can have objects moving in opposite directions; for example, one may have a momentum of +100 units, and the other, a momentum of -100 units.

When they travel in different directions, obviously, since velocity is made up of a speed and a direction.

Nothing. The momentum of individual objects may change but total momentum is conserved.

In order to increase an objects momentum, you must increase the objects velocity or mass. To decrease momentum, you reduce the objects velocity or mass.

Mass is the measure of how much matter an object is made from. Velocity is the speed of an object in a particular direction. Momentum is the the Mass of an object multiplied by its velocity. A stationary object with a mass of 1 and velocity of 0 has a momentum of 0 because 1 X 0 = 0. An object of mass 1 and velocity 2 has a momentum of 2 because 1 X 2 = 2. If the object of momentum 2 hits the object of momentum 0, the velocity of both objects is shared, which means the both objects have a velocity of 1. The mass of both objects is unchanged so the momentum of both objects equals 1 because 1 X 1 = 1. The combined momentum of the two objects is 2 because 1 + 1 = 2. The original momentum of both objects was 2 because 2 + 0 = 2. The momentum after the objects hit each other is 2, which means the momentum as not changed, this is what the the law of conservation of momentum means. The law is true for objects of different mass and if both are moving with different velocities and for more than two objects colliding.

If all objects have energy as in E=mc^2 then all objects have momentum P= mc. The universe consists of two types of "objects" scalars and vectors. Scalar momentum =mc, and Vector momentum =mv. If you only consider vector momentum then only objects with velocity have momentum. Here the problem is the Relativity of velocity. If there is no relative velocity then there is no vector momentum. There still is scalar momentum mc for all objects.

Rotating objects all have angular momentum.

It can't. The total combined momentum is equal to the sum of the momenta of the individual objects.Please note that momentum is a VECTOR quantity; that means that you can't even say whether a momentum is "larger" or "smaller" than another one. You can only compare the MAGNITUDE of the momenta with words such as "larger" or "smaller".

Yes. The total momentum would be the same. This is an example of the conservation of linear momentum.

No. Speed is the magnitude of the velocity vector. In order for two velocities to be equal, they must have equal magnitudes and equal (parallel) directions.

Yes: P=mv (momentum = mass * velocity)

Objects with different masses can have the same momentum, m1v1 = m2v2.

One object that has a momentum is a computer.

Momentum is not an object, it is energy.

The law of conservation of momentum states that the total momentum of a group of objects does not change unless outside forces act on the objects.

Assuming all of the objects have the same mass, the answer depends on their combined velocities. If the combined vector component of velocity of two objects is the same as the velocity of the single moving object, then the force of impact will be the same. So if the two are moving in opposite directions along the same path, they will generate the same amount of force as a single object moving at a velocity that is equal to the combined velocities of the two. If the velocities are different, the force varies accordingly.

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.
