physics test notes (speeding up)

notes for physics test Acceleration/deceleration,slowing things down forces,friction and speed acceleration is the change of velocity divided by time (velocity/time) use the terms drag, friction and unbalanced force,acceleration and know how they affect the acceleration of a object streaming and air resistance show when terminal velocity occurs (draw arrows to show the forces acting change over the fall. how fast something moves speed = distance/time state the different units of speed know and use the triangle equation recognize that if you apply an unbalanced force to something you change is speed or direction.
