    What is the product of mass and velocity of an object?
    Linear momentum is defined as the product of a system`s mass multiplied by its velocity. In symbols, linear momentum is expressed as p = mv. Momentum is directly proportional to the object`s mass and also its velocity. Thus the greater an object`s mass or the greater its velocity, the greater its momentum.
