At the county fair, Carrie and Sam climbed up on the carousel horses. Around and around they went; the horses also bobbed up and
down. When they got off of the carousel, Carrie told Sam they had been accelerating during their ride. Sam disagreed; they had been moving at a constant speed. Whose response is fully correct, and why?
I believe sam's response is correct. When human is riding a moving target with constant speed over a period of time, we tend to have a visual acceleration perception due to our optical movement. This make people such as Carrie believes that the carousel horses are accelerating while it actually stayed at constant pace.
