Horses live in nearly every part of the world. They live in the  United States, Europe, Germany, Canada, and many other countries.
Impulse & Momentum. Summary. 1  is a quantity that describes an object's resistance to stopping (a kind of moving inertia). 2  is represented by the symbol p (boldface). 3  is the product of an object's mass and velocity.  is a vector quantity (since velocity is a vector and mass is a scalar).
Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. In physics, the symbol for the quantity momentum is the lower case p.
