Have the passenger ready with stopwatch and paper to record data. 3. Have the driver accelerate up to above 70 km/h or so, and shift into neutral. 4. Record data as follows. The driver should indicate when the speed drops to exactly 70 km/h. At this time (t=0) the passenger should start the clock. changeling jewelry co

"WebIntroduction The drag force on an object is produced by the velocity of a liquid or gas approaching the object. Drag force is dependent upon the drag coefficient of the object and the geometry of the object. For some objects, the drag coefficient is independent of the object's dimensions.
