The coefficient of drag (Cd)is _____.
A)the total resistance to motion caused by air friction
B)the rate of acceleration divided by time
C)the distance a vehicle travels divided by time
D)the amount of horsepower an engine produces divided by the friction of the driveline

Question

Quizplus · Accepted Answer

The coefficient of drag (Cd) is a dimensionless number that quantifies the drag or resistance of an object in a fluid environment, such as air or water. It is used to model the drag force, which opposes an object's motion through a fluid. This coefficient is crucial in aerodynamics and automotive design to minimize resistance and improve efficiency. Choices B, C, and D describe different concepts unrelated to the coefficient of drag.
