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 All objects have momentum true or false?
False. Not all objects have momentum. Momentum is a property of moving objects and is defined as the product of an object's mass and velocity. Objects at rest do not have momentum.
Explain how momentum is conserved after collision?
In a collision, the total momentum of all objects before the collision is equal to the total momentum of all objects after the collision, provided no external forces are acting on the system. This is described by the principle of conservation of momentum, which states that momentum is neither created nor destroyed; it is simply transferred between objects during a collision.
How does the conservation of momentum symmetry apply in the context of physical interactions between objects?
The conservation of momentum symmetry states that in a closed system, the total momentum before a physical interaction between objects is equal to the total momentum after the interaction. This means that the combined momentum of all objects involved remains constant, showing that momentum is conserved in the interaction.
How can multiple objects have a net momentum of zero?
Multiple objects can have a net momentum of zero if their individual momenta cancel each other out. This can happen when objects are moving in opposite directions or when the magnitudes of their momenta are equal but opposite. In this scenario, the total momentum of all the objects in the system sums to zero.
How does the conservation of momentum apply to a closed system?
The conservation of momentum states that in a closed system, the total momentum remains constant before and after any interaction between objects. This means that the total momentum of all objects in the system does not change unless acted upon by an external force.
