That means that a quantity, called "momentum", can be defined, and that this quantity does not change over time. In any collision, for example, the momentum (which is defined as mass x velocity) of individual objects can change, but the total momentum does not change. Please note that since velocity is a vector quantity, momentum is also a vector quantity.
Force. The way Newton specified his law originally, force is equal to the derivative of momentum with respect to time (dp/dt) - that is, to its rate of change.
It means that the momentum increases, decreases, or simply changes its direction. The latter is because momentum is a vector quantity (that is, the direction is relevant). Momentum is defined as the product of velocity and mass.
Two reasons. Recall impulse is the change in momentum. First the momentum is a vector. So imagine a triangle. One side is the initial momentum (with one direction), the second side is the final momentum (with a potentially different direction) and the third side is the impulse (or change in momentum). The other way to look at this is in terms of what causes the change in momentum. This is how impulse is generally described. The impulse can be defined as the average force acting on the particle multiplied by the time interval over which the force acts. This is sometimes represented as the integral of the force. As force is a vector so is the impulse caused by this force.
Force and rate of change of momentum (both vector quantities) are cause (force) and effect (rate of change of momentum). Newton's second law of motion equates the two quantities, but they are not identical. There is a distinction in that forces derive from interactions between objects (gravitational, electrical, magnetic...) while momentum changes in response to the net force acting on an object or system.
It means that there is a quantity called momentum; the total quantity of which doesn't change.

Velocity of satellite and hence its linear momentum changes continuously due to the change in the direction of motion in a circular orbit. However, angular momentum is conserved as no external torque acts on the satellite.

Volume is a physical quantity not a change. However CHANGE in volume is a physical change.

Total momentum in an isolated system does not change. The law of physics. The law of conservation of momentum explains that momentum is neither lost of gained. That means that there is a quantity, called momentum, that is conserved.

In a uniform circular motion,the magnitude of velocity remains constant,that is speed is constant,however due to change in direction in circular path constantly the motion is accelerated due to change in velocity.
