The video below shows four future ME 274 students playing on a merry-go-round with a ball. The video is split between two views: one from a stationary observer looking down from above, and the other from a rotating observer on the merry-go-round. The stationary observer sees a straight path. The moving observer sees a curved path. Why is that? What influences the shape of this path?<\/p>\n

Analysis<\/strong><\/em><\/p>\n

Provided is a solution video for this problem, showing the influence of the Coriolis component of acceleration on the moving reference from observation of the ball. Click here to watch<\/a>.<\/p>\n

Results<\/strong><\/em><\/p>\n

As shown in the analysis, a ball pushed directly toward the center of the merry-go-round will appear to have an acceleration to the left. This will produced a perceived curved path of the ball for people riding along on the merry-go-round.<\/p>\n

Simulation<\/strong><\/em><\/p>\n

The simulations below allow us to compare and contrast the view of the path of the ball as seen by a stationary observer, with the ball’s path as seen by a person riding on the (rotating) reference frame of the merry-go-round. These observations agree with those initially seen by the videos of the children playing.<\/p>\n\n\n\n
