Modue target The subject matter of the modue covers the issues concerning basic car motion. As part of the modue, the issues of ongitudina motion dynamics are discussed. The fundamentas of the car braking theory are discussed as we. The modue aso incudes such issues as car curved-ine motion as we as the notions of maneuverabiity, controabiity, steerabiity, and stabiity (incuding the phenomenon of side drift of a tyred whee). Perpendicuar dynamics of a car wi additionay be discussed.
