College Physics - Core Concept Cheat Sheet 08: Momentum and Collisions Key Physics Terms Conservation of Momentum in 2D Vector:  A quantity that represents magnitude (size) and direction. It  is usually represented with an arrow to indicate the direction; arrow  may be drawn to scale. Vector Component:  The perpendicular parts into which a vector can be separated and that act in different directions from  the vector. Resultant:  The result of adding two or more vectors; vector sum. Vector Addition : The process of combining vectors; added tip to  tail. Force : A vector quantity that tends to accelerate an object; a push or a pull. A Ball a strikes A B motionless ball B. After the collision they move off as B shown. Note how momentum is conserved.  In the x-direction, the  momenta add up to the original momentum before the collision.  In  the y-direction, the momenta cancel out since there was no
