Match the following vocabulary 1. a force applied by a surface that is perpendicular to that surface friction force 2. a pulling force force 3. a rubbing force between the surfaces of two objects newton's first law 4. a diagram of force vector arrows that indicates the direction and magnitude of all forces acting on an object or system newton's second law 5. if the forces that act on an object cancel each other out then the motion will be constant velocity – this also includes a constant velocity of zero free body diagram 6. if the forces that act on an object don’t cancel each other out then the object will accelerate – the object will either speed up or slow down normal force 7. a push or a pull tension force
