If two objects have the same velocity do they have the same momentum?
Jeiry
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.)

Do two objects that have the same mass and velocity always have the same momentum?
yes
Do Two objects of different masses freely fall with same momentum?
No.....because we need both mass and velocity to find the momentum if velocity is same that is 9.8m/s that is of free falling bodies.........mass will effect the final result.
A measurement of the motion of something. This is equal to the product of the moving objects's mass times it's velocity?
== == Momentum is the product of the mass of an object multiplied by its velocity (or speed). Momentum is conserved so if a moving object hits a staionary object the total momentum of the two objects after the collision is the same as the momentum of the original moving object.
How can it be possible for two objects with different velocities to have the same momentum?
The momentum product can be the same with different velocities; m1V=m2rV thus m1/m2=r ratio with V1=rV1.
Can objects with different masses have the same momentum?
Yes. Momentum is rigidly defined as the product of mass and velocity. Velocity describes both a speed and a direction. So let's take two metal balls. One weighs 10 kilograms (kg) and the other weighs 20kg. We roll the 10kg ball along a flat and level floor at 2 meters per second (m/s) and the 20 kg ball at 1 m/s. 10*2 = 20*1 so they have the same momentum. If you have a friend roll the balls for you to catch some distance away, making sure after a few tests to roll the lighter ball at twice the speed of the heavier ball, you will find that it "feels" as if both balls hit your hand with about the same force. Your hand is stopping each ball. That is a force which is defined as the rate of change in momentum. Stopping each ball will cause your muscles to exert about the same strength to stop each ball, even though one is moving at double the speed of the other. You will then feel that two objects can indeed travel at different speeds and yet have the same momentum. JGS
What is a momentum of an object of mass 'm' moving the velocity v?
Momentum is mass times velocity. Note that velocity and speed are not exactly the same thing. Velocity is a term used in physics to define both the speed and the direction of a moving object, so if two objects are moving at the same speed but in opposite directions, they have opposite momentum.
Why do you need momentum?
Momentum is defined as the "Mass in Motion". It is a Vector quantity. It depends on two variables (Object Mass and Velocity) . Its direction is same as objects velocity direction. In physics momentum is required to specify the motion of the object . If two bodies of same masses having different velocities have different momentum , in a similar way bodies of different masses having same velocity have different momentum. So , in order to describe the motion of object clearly one of the tool in classical mechanics is momentum
What happens to the total momentum of two objects in a system before and after interactions?
The total momentum before the collision is the same as the total momentum after the collision. This is known as "conservation of momentum".
If two objects have the same momentum do their magnitudes necessarily have the same directions?
First 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.
Which truck has more momentum a 2000kg truckor a 2kg truck?
That would depend on their velocity (speed with direction), since the formula for momentum is momentum=Mass*Velocity. If they are moving at the same Velocity, the heavier of the two would have greater momentum.
Will two cars of different engine capacities maintain the same momentum if driving at the same speed?
Momentum is velocity times mass, so, in order for two cars to have the same momentum at the same velocity, they must have the same mass. Engine capacity has nothing do do with the equation.
Relatinship between velocity and momentum of the object?
With any two of the three values of velocity, momentum and mass, the third can easily be calculated. (Momentum) = (Velocity) x (Mass) If you were to multiply the velocity by some factor, the momentum would also be multiplied by that same factor. These are directly proportional.
