← ScienceWhich outcome increases behind a racing car when approaching terminal velocity?
A)Separation resulting from turbulent flow✓
B)Boundary layer remaining completely laminar
C)Aerodynamic lift exceeding vehicle weight
D)Decreased pressure raising vehicle stability
💡 Explanation
A turbulent wake increases separation because the increased kinetic energy disrupts attached flow, therefore pressure drag is larger rather than pressure lowering, due to laminar flow’s lower resistance around streamlined objects.
