Vin Baccelli | Tennis Coach 🎾 on Instagram: "POV: your student brings a drone to practice 🎥 This is one of the few ways to measure separation angle accurately. From the side, you see rotation. From above, you can measure it. Shoulders vs hips. Exact angles. No perspective distortion. This is why overhead + side view together give a true technical breakdown — especially for spin mechanics. If you’re serious about building a consistent, fault-tolerant stroke, this kind of analysis changes everyt

Engineering | Science | Technology on Instagram: "It all comes down to angular momentum. When the gyroscope spins, its mass creates a force that resists changes to its orientation. That’s why, even though it looks like it should fall over, it stays balanced on a tiny point. The faster it spins, the stronger the effect — and the more stable it becomes. Engineers and scientists use this principle in everything from navigation systems to spacecraft, because a spinning object can maintain direction
