How could two objects travailing at the same speed have different amounts of momentum?

Momentum is a vector and so obeys the laws of vector addition. These imply that the momentum of two two objects will be the sum of the individual momentum only if the objects are moving in the same direction.

∙ 7y agoIt 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".

What depend on objects mass and velocity?
a moving objects momentum
Can momenta cancel?
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.
The total amount of momentum of a group of objects does not change unless outside forces act on the objects?
Momentum
Is an objects momentum directly proportional to an objects velocity?
Yes: P=mv (momentum = mass * velocity)
How does the momentum of two objects before a collision compare with the momentum after the collision?
conservation of momentum
Momentum of a system is conserved only when?
When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.
What would cause objects that have the same mass to have different amounts of inertia?
Different velocities is what causes objects to have the same mass and different amounts of inertia. This can be written in a formula.
What depend on objects mass and velocity?
a moving objects momentum
What would cause objects that have the same mass to have different amounts of intertia?
If the objects have different velocities they will have different inertia.
If two objects have the same velocity do they have the same momentum?
No, because momentum depends on velocity and mass so they may have the same velocity but if they have different masses then they will have different momenta. (momenta is the plural form of momentum.)
Can momenta cancel?
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.
Do all rotating objects have angular momentum?
Rotating objects all have angular momentum.
What do different numbers mean?
Different numbers represent different amounts. These amounts can be years, days, objects, sizes, and anything else that can be measured.

What kind of objects have momentum?
One object that has a momentum is a computer.
