Now no longer available from Dell as a new system purchase, but is in factory outlet. This desktop at one time filled the gap between the media-oriented XPS 420/430 and the high-end XPS 730x. There is no physical difference(s) between the 630 and the 630i.

Inertia is the resistance of object to change in its current state to the next state. or you can say that ability to resist the acceleration is called inertia. Force = mass* acceleration (here mass gives the quantitative measure of inertia.) while momentum is related to the state of motion of object only. Momentum = mass * velocity ( here mass gives the quantitative measure of inertia but product of inertia and velocity gives quantitative measure of momentum).
