... In Newtonian mechanics, space, time, and mass are absolute concepts, independent of each other. (This is not true in relativistic mechanics, where the time of an event depends upon its position, and where the mass of a body varies with its velocity.) On the other hand, the concept of force is not in ...

Momentum - Jobworks Physics
... Momentum can be defined as "mass in motion." All objects have mass; so if an object is moving, then it has momentum - it has its mass in motion. The amount of momentum which an object has is a product of two variables: how much mass is moving and how fast the mass is moving. Thus momentum is a produ ...
