Ken Kuwako, your Science Trainer, here. Every day is an experiment! Say the word “gyro,” and what pops into your head? A spinning top? A bicycle? Maybe a spacecraft adjusting its orientation? Here’s the thing: in the world of physics, “gyro” actually shows up with at least four different meanings. No wonder it’s confusing! Today, […]

Ken Kuwako, science trainer, here. Every day is an experiment! Wrap a rubber band around a paper cup, let it go, and whoosh! Did you know the cup spins as it flies and sails along in a perfectly straight line? No wings, no propeller, yet a humble paper cup flies like an airplane. The secret […]

Ken Kuwako, Science Trainer. Every day is an experiment. The Magnetic Field Made by Electric Current: Uncovering the Link Between Electricity and Magnetism Did you ever play with a magnet and iron sand at the sandbox as a kid? Chances are that mysterious pull got you pretty excited. And what about rubbing a plastic pencil […]

“If your speed doubles, how much harder is the crash?” When car accidents make the news, “excessive speed” is often blamed. That’s because even a small increase in speed makes the impact far worse than you’d expect. The secret behind it is something familiar from physics class: kinetic energy. So what does kinetic energy depend […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment. Every time I do this experiment, I can’t help but say, “Wow!” There’s electric current that we can’t see, and there’s a magnetic field that we can’t see either. Yet when these two “invisible things” meet, something amazing happens: a real force appears. And […]
