Unbalanced Forces, Acceleration

When a car goes around a corner at a constant 20 mph, why do we say it accelerates?

The car is accelerating because it's changing direction

The car is accelerating because of the velocity is constant

The car accelerates because it's going 20 mph

Cars always accelerate when they are in motion

opposite to the direction of the motion

in the same direction as the motion

the same direction as the applied force

change the direction of the motion
