Aferris wheel is turning at a constant speed. the riders are accelerating.

The riders are radially accelerating.

Explanation:

The Ferris wheel is making a circular motion. If it is moving with constant velocity, than the acceleration is

towards the center of the wheel.

So, the riders are subject to a constant and radial acceleration, which is called the centripetal acceleration.

a

explanation:
