Do all objects have a momentum?
No. An object has momentum only if it is in motion..There are two kinds of momentum: linear momentum(or translational momentum), and angular momentum (or rotational momentum)..Linear momentum is a vector quantity and is calculated as mass x velocity (p = mv). Therefore, if an object's velocity is zero, then it has no linear momentum, but if an object is in motion, then it does have linear momentum..VERY IMPORTANT NOTE: Velocity, and therefore linear momentum, is always relative to the frame of reference. For a more complete discussion about velocity, see the related answer, referenced below, entitled 'How to Find Velocity'..Angular momentum is a pseudovector quantity that describes the momentum of an object that is spinning or rotating in place. An object has angular momentum only when it is spinning, or rotating about an axis. When an object is not spinning or rotating, then it does not have angular momentum..It is possible for an object to have only linear momentum, only angular momentum, or both angular and linear momentum. Note that this discussion falls apart in quantum mechanics, so we are only discussing classical physics - that is, every day observable objects, and not light particles (photons), electrons, or other quantum particles..All objects do have inertia, which is a resistance to a change in its momentum.
How does mass affect angular momentum?
Short answer: Angular momentum is proportional to mass. If you double the mass of an object, you double its angular momentum.Long Answer:Angular Momentum is a characteristic of rotating bodies that is basically analogue to linear momentum for bodies moving in a straight line.It has a more complex definition. Relative to an origin, one obtains the position of the object, the vector r and the momentum of the object, the vector p, and then the angular momentum is the vector cross product, L.L=r X p.Since linear momentum, p=mv, is proportional to mass, so is angular momentum.Sometimes we speak of the angular momentum about the center of mass of an object, in which case one must add all of the bits of angular momentum for all the bits of mass at all the positions in the object. That is easiest using calculus.It should also be said that the moment of inertia, I, is proportional to mass and another way to express angular momentum is the moment of inertia times the angular velocity.
If something shrinks in size but not in mass what happens to its angular momentum?
Angular momentum is maintained in such a case - and in fact in all cases, unless angular momentum is transferred to, or from, another body. This means it must rotate faster.Angular momentum is maintained in such a case - and in fact in all cases, unless angular momentum is transferred to, or from, another body.

What is the angular momentum of the 2.6 kg 5.6 cm diameter rotating disk.?
Without knowing the angular speed, i.e. RPM or some such velocity, it is not possible to answer the question. Please restate the question, giving all of the required information.
Which way does the earth rotate and why?
counter-clockwise. All the the objects in the solar system orbit in that direction and almost all of them rotate in that direction. This due to the conservation of angular momentum.
Does linear motion have angular momentum?
I believe that any particle in linear motion must also have some angular momentum because all particles have spin. In the case of a photon the spin, wavelength and angular momentum all vary with the relative linear velocity. So in my point of view time itself is the ratio between relative linear and angular momentum.
All moving objects have?
All moving objects have Momentum.
What is gravitational force and angular momentum?
No one knows WHAT it is, but its the "force" that causes all matter to attract all other matter. Angular momentum is a measure of how much work it would take to make something stop spinning.
Why does the world spin on its axis?
Mainly because any object that is spinning has a tendency to continue spinning. This is called conservation of angular momentum. The initial spin must have come when the planet was formed; different objects crashed together, forming the planet, and it is very unlikely that all of these crashes were exactly in the center of the newly-forming planet, so there was a random net angular momentum.

When objects collide total momentum of all objects what?
Remains constant.
Why is the Milky Way shaped like it is?
The Milky Way galaxy consists of stars, planets, and other objects all revolving around the galaxy's center of mass, held in place by the balanced forces of gravity and angular momentum. The angular momentum is ultimately derived from the Big Bang. The specific details of why the galaxy is shaped as it is are the result of a long series of chaotic and unpredictable random events.
