I’m Ken Kuwako, your Science Trainer. Every day is an experiment!<\/strong><\/span><\/p>\n

Have you ever felt a mysterious force pinning you against the side of a spinning teacup at an amusement park, or felt yourself leaning outward as a car takes a sharp turn? It\u2019s that “whoa!” moment where you instinctively brace yourself. Believe it or not, there is a “ghostly force” in our world that appears simply because the spot where you are standing is rotating.<\/p>\n

Recently, I streamed an online lesson on Uniform Circular Motion<\/a>, a fundamental concept in physics. In that lesson, I used a rotating table to explain the mechanics of circular movement. But today, I\u2019m taking it a step further. I\u2019ve filmed an experimental video to answer the question: “What does the world actually look like from the perspective of someone on a spinning object?”<\/p>\n

The Experiment: Catching the “Ghost Force” Known as Centrifugal Force<\/h3>\n

The star of this experiment is a weight attached to a spring, fixed at the center of a rotating table. By watching whether the spring stretches or stays still, we can visually confirm if a force is at play.<\/p>\n

To make things interesting, I focused on the “difference in perspective”:<\/p>\n

A camera standing perfectly still outside the table (Stationary Frame).<\/p>\n

A camera spinning right along with the table (Rotating Frame).<\/p>\n

By recording these two perspectives simultaneously and comparing them side-by-side, we can uncover the true nature of one of physics’ great mysteries: “Centrifugal Force.” After a lot of trial and error, I finally captured the perfect footage. First, take a look at this striking comparison video:<\/p>\n
