Meaning of Momentum:
An object that has momentum has its mass in motion. The amount of momentum that the object has depends upon how much mass it has and how fast that mass is moving.


 
Lots of things could be true of an object that has momentum. For instance, it could be colored red, have four wheels and be located in Illinois. But obviously not every object that has momentum is red, has four wheels and is located in Illinois. We wish to identify not what could be true of an object that has momentum, but what one can be sure is true of an object that has momentum. To meet the definition of having momentum, an object must be moving. Momentum is mass in motion. To have momentum an object (which is guaranteed to have mass) must be moving.
