Velocity remains constant if no external force acts.
It's the mass of a object on its velocity (the velocity is a vector and as result of multiplication of a scalar (mass) on a vector (velocity) you get a vector (momentum). Intuitively, momentum is the property of a body which enables it to resist a force.
That means that there is a quantity, called momentum, that is conserved. Momentum is defined as the product of mass times velocity. If you add (product x velocity) for several items, or particles, before and after a collission for example, the total you get will not change. Note that, since velocity is a vector quantity, so is momentum, so if your items move in more than one dimension, you have to use vector addition.
If there are no outside forces acting on a system of particles the total momentum of the system will remain constant; i.e. the center of mass of the system will remain at rest or move at constant velocity.
By increase the objects mass and its velocity, Since Impusle (F x t) is the change in momentum and momentum is (Mass x Velocity) Impulse depends on the magnitude of the applied external force and the time that the force acts on the system. By increasing either of those, impulse on a system will be increased, and the system's momentum will change accordingly.
Isolated System
Yes - and if no external forces act upon the system - the center of mass of the system remains constant

The question cannot be answered because you need a fixed reference point against which to measure the speed (or velocity) of the earth through the universe. What would this be? The sun (or centre of the solar system)? But that travels round the centre of the Milky Way Galaxy. The centre of Milky Way? But that travels around the centre of our local cluster. The centre of our local cluster? No, because that travels round ... and so on.
There is a wide difference between the internal system unit and the external system unit. The internal system unit is usually mounted on the motherboard inside the computer while the external system unit is independent of the computer like an external drive.
As long as the system is periodic, velocity will have no effect on the period.
The two external controls of the circulatory system is the house.
MVW: Medium Velocity Water spray system HVW: High Velocity Water spray system
breathing is regulated by the respiratory control centre (RCC) which detects signals from the chemoreceptors and proprioceptors, the RCC then sends a signal to the inspiratory centre and the expiratory control centre to either contract the external intercostal muscles and phrenic nerves to breathe out or relax the internal intercostal muscles and abs to breathe in.
The linear momentum of a system of particles is simply the vector sum of the linear momentum of each of the particles.
