3.6 | Unlock Orbital Speed: Launching Rockets | Rocket Science for Everyone with Marla Geha
Ever wondered how rocket scientists squeeze every bit of speed out of a launch? In this lesson, we explore a clever way to increase a rocket's final velocity: by selecting the optimal launch site on Earth. We'll uncover how taking advantage of our planet's rotation can provide a significant boost to a rocket's delta-v, allowing for more ...

🔥 Why Hip-to-Shoulder Separation Is the Secret to Velocity AND Arm Health ⚾️ We tested it with Trackman: 👉 No separation (hips shoulders rotate together) = lower velo, more drag on the arm. 👉 With separation (hips fire open, trunk stays back) = 3 MPH velo, better spin, and way less stress on the arm. 💡 Here’s why: When your hips and shoulders rotate together, the arm has to drag and force rotation = more stress less velocity. When you separate, your trunk delays & drives the whip, so the arm
