A person on a merry-go-round is constantly changing direction true or false?

True. A person on a merry-go-round is constantly changing direction as the ride rotates. The merry-go-round's circular motion causes the person to experience a continuous change in the direction they are facing. As the ride spins, the centripetal force acts on the person, pulling them towards the center of the circular path, leading to a constant change in their orientation.
