Momentum

Momentum, abbreviated as p, also called linear motion or translational momentum, of an object is the amount of mass in motion.  Momentum is a vector quantity having magnitude and direction, some of these include acceleration, displacement, drag, force, lift, thrust, torque, velocity, and weight.  The change in momentum is called impulse.

Practically, momentum is the measure of inertia for objects in motion.  It helps quantify how difficult it is to stop something.  It is commonly used in a derivation of Newton's First Law where there is no change in momentum if there are no outside forces acting on a system. 

 

Momentum Types

• Angular momentum
• Conceptual momentum
• Linear momentum

 

Momentum diffusion

Momentum diffusion also known as diffusion, or spread of momentum between particles (atoms or molecules) of matter, often in the liquid state. In fluids, this is caused by viscosity.
