Momentum (p) is a product of an object''s mass (m) and its velocity (v): p = m v. In other words, momentum is a product of a mass in motion. Momentum also has direction associated with it and is considered a vector. For example, we can calculate the momentum of a 2000 kg car heading north at a speed of 20 m/s.
