No, the magnitude will be constant, but the direction of the momentum will change to reflect the direction of the velocity.

Why its easy to turn along a curved path of large radius as compared to the curved path of short radius?
The magnitude of centripetal force is calculated by the relation Fc=mv2/r where m is mass of the object,v speed of the object (constant) and r radius of the curved path.If the radius of curved path is large then centripetal force is decrease. Therefore it is easy to turn along a curved path of large radius as compared to a curved path of short radius.
Which component of linear momentum does not contribute to angular momentum?
Angular momentum is defined as the moment of linear momentum about an axis. So if the component of linear momentum is along the radius vector then its moment will be zero. So radial component will not contribute to angular momentum
Why are forces balanced when traveling at a constant speed?
If there be net force then it has to be accelerated. So the magnitude of the speed cannot remain the same. But in case of a body moving with a constant speed along the circular path, the forces will be centripetal and centrifugal both acting in opposite direction. So the body would not have displacement along the radial path.
A freight train rolls along a track with considerable momentum If it were to roll at the same speed but had twice as much mass it's momentum would be?
Twice.
What does Momentum do?
Momentum is basically the amount of force it takes to slow something down. Force is Mass times Acceleration, so weight and speed are a factor. A large object like a bus, moving at even a slow speed has a lot of momentum. It would take a lot of force to slow it down. A bullet would have a fair bit of momentum because of it's high speed, but not because of it's low weight. A bus traveling at the speed of a bullet would have a rediculous amount of momentum.

If an object moves along a curved path at constant speed is a force is acting upon it?
Yes. The centripetal force acts on any body moving along a curved path. It acts along the radius of the path and is pointed towards the centre. If friction is in the equation there will need to be a force behind the object to counter the slowing effect as well.
If the speed of an object does not changed then the object is traveling at a?
If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
What are some forces that would influence momentum?
Any force that acts along or has a component along the direction of the velocity vector will influence momentum.
How many curved edges does a cylinder have?
There is one curved side and two curved edges (the rims along the top and bottom).
