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 is the quantity of motion of a moving body. It is expressed mathematically as p = m * v, and has units of kg m/s. The principle of conservation of momentum states that in an isolated system, two objects that collide have the same combined momentum before and after the collision.
