Happy Fact One on Instagram: "The video demonstrates a leverage technique for lifting heavy car tires, where mechanics insert a pry bar under the rim to apply torque, shifting the tire's center of mass and reducing required force by up to 90% compared to direct lifting. Rooted in Archimedes' principle of the lever—torque equals force times distance—this method exemplifies mechanical advantage, as confirmed in physics resources like Feynman's Lectures on Physics, turning a strenuous task into an

Explainer Zone on Instagram: "Prof. Walter Lewin, the renowned MIT physics professor, often demonstrated the gyroscope effect in his lectures to show the fascinating laws of rotational motion. In his demonstration, he would hold a fast-spinning bicycle wheel by a handle and then let go of one side. Instead of falling due to gravity, the wheel would begin to precess—slowly rotating around a vertical axis. This surprised many students, as it clearly showed how angular momentum and torque govern th
