"Force" is an influence that causes mass to accelerate. It may be experienced as a lift, a push, or a pull. Force is defined by Newton's Second Law as $F = m \times a $, where $F$ is force, $m$ is mass and $a$ is acceleration. Net force is mathematically equal to the time rate of change of the momentum of the body on which it acts. Since momentum is a vector quantity (has both a magnitude and direction), force also is a vector quantity.

$F = \frac{dp}{dt}$, where $F$ is the resultant force acting on a body, $p$ is momentum of a body, and $t$ is time.
