Physics Uncovered on Instagram: "Pascal’s law is one of those quiet principles that secretly powers the modern world. When you apply pressure to a fluid inside a closed system, that pressure spreads equally in every direction — no loss, no shortcuts, just perfect transmission. 💧⚙️ Hydraulic systems take advantage of this by using a small piston to create a big effect. Push lightly on a small area, and that pressure multiplies into a massive force on a larger piston. It’s the reason car brakes s
