How to Calculate the Mechanical Advantage of a Lever | Physics | Study.com

science on Instagram: "When athletic brilliance meets fluid dynamics! This demonstration of a high-speed football goal proves that even the most complex defensive blocks can be bypassed through the science of lift, turbulent wakes, and mechanical energy summation! ⚽️💨 What you’re seeing here is a masterclass in elite ball manipulation where a player utilizes either a curved strike or the elusive knuckleball—a situation where the physics of atmospheric pressure and boundary layer separation dete

Oscar Saucedo on Instagram: "Why your Lateral Raises suck (It’s Physics). 📐The lateral raise isn’t about moving weight from point A to point B. It is a Third-Class Lever system. In this system, the Effort (your deltoid insertion) is located between the Fulcrum (glenohumeral joint) and the Load (dumbbell). This creates a mechanical disadvantage. As you abduct the arm, the moment arm lengthens, maximizing torque at the shoulder joint when the arm is parallel to the floor. If you use momentum to s
