I’m Ken Kuwako, your Science Trainer. Every Day is an Experiment! What would happen to objects if friction suddenly vanished from the world? You’ve learned about the Law of Inertia in your textbooks: an object will continue to move in a straight line at a constant speed unless acted upon by a net external force. […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment. The God of Science often smiles upon us in unexpected moments of daily life. Take a look at this video. The movement here clearly illustrates the Law of Inertia—that “an object in motion stays in motion unless acted upon by an external force.” The […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment. The Wonder of Science Awaits You at the Park Pond! On a beautiful day, when you casually stop by a park pond, you’ll see schools of brightly colored koi swimming serenely. As soon as someone approaches, they gather as if drawn by a magnet. […]

I’m Science Trainer Ken Kuwako. Every day is an experiment. The “Tablecloth Pull” is always a massive hit during physics classes. It’s breathtaking to watch someone whip a cloth out from under a set of dishes, leaving them sitting there as if by magic. It’s a trick that makes everyone hold their breath, thinking, “If […]

I’m Ken Kuwako, your Science Trainer. Every Day is an Experiment. What image comes to mind when you hear the phrase, “The Law of Inertia”? Many people would probably answer, “That feeling when a bus slams on the brakes and you lurch forward!” The textbook definition is often difficult to grasp, stating that “an object […]
