Imagine a car crash. A car coming at a high speed has a head on collision with a car at rest. When the car makes impact, it will move the other car with it at a slower speed then it was travelling at. In this case, the velocity decreased since the car slowed down, but the mass increased since there are now two cars moving. Momentum was conserved because the change in mass accounts for the loss of velocity.

The philosophy is
simple that no one can start the journey towards being a Muslim unless he
professes the basic principles mentioned in the "Declaration of
Faith", which is "<span>“There is none worthy of
worship but Allah and Muhammad is His Messenger”.
The declaration consists of the two most fundamental elements of Islamic ideology:
1) Unity of Allah: Declaring that there is only One God and none else is mandatory
to be a Muslim.
2) Faith in the prophet hood of Muhammad, the messenger of Islam.</span>
