Suppose you have a car traveling down the road at constant speed and not changing direction. It is experiencing gravity, wind resistance and frictional forces from the road. What can be said about the car's acceleration?
A) It is accelerating because there are forces acting on it.
B) It accelerating because the motor is running, propelling the car forward.
C) It is not accelerating because gravity holds it down.
D) It is not accelerating because it has constant velocity.
