Do two objects that have the same mass and velocity always have the same momentum?
yes
A car and a train are traveling with the same velocitydo the two objects have the same momentum?
No, the train has MUCH more mass and momentum is mass times speed.
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
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.
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.

Is it possible that have the different mass always have the same momentum?
Not always, but they do have the same momentum when the product of the mass and speed of each is the same number. So a larger mass can have the same momentum as a smaller mass if it's moving faster. Simple example: A rifle bullet can knock a large animal down.
Do objects of the same size always have the same mass?
not always it depends
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.)

Does an object on earth have the same mass as it does on the moon yes or no?
Yes. Mass is intrinsic to objects wherever they are. Weight and momentum can change with position.
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.

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.
Does a 1 kilogram ball or a 10 kilogram ball have more momentum?
Inertia is directly proportional to mass. Unless you mean rotational inertia, in which case it depends on the shape, but for two objects of the same shape (and mass distribution), the more massive always has higher inertia.
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.
