Definitions for

**"Linear momentum"**the product of mass and velocity.

The object's mass multiplied by its linear velocity.

The kinetic energy of an object multiplied by its 3-component direction vector oriented by some reference axes: Linear momentum ("p") p = ( 1 / 2 ) * m * ( v ^ 2 ) Where: p = linear momentum vector m = mass in kilograms v = velocity vector Normally expressed in Cartesian vector form having both direction and magnitude: p = 1.23i + 3.45j + 6.78k Because this represents energy, the units are Joules.
