Friction - The force that always opposes motion Coefficient of friction - Force of friction divided by normal force Net force - Resultant force, the sum of all forces acting on an object Free body diagrams - Physical model of a representation of forces acting on a system 2-dimensional motion - Any motion of an object is more than one line, a plane Vector independence - Changes in one vector do not cause changes in another Projectile - Any object launched into the air with no force other th...
