🧭 Pressure Diagrams

Two side-by-side diagrams on a dark backdrop. Left panel 'Same force, different area': two identical 50N blocks sit on surfaces. The left block has a small contact area (amber, like a stiletto) producing 50,000 Pa — HIGH pressure. The right block has a large contact area (cyan, like a flat shoe) producing 1,000 Pa — LOW pressure. Right panel 'Pressure increases with depth': a water tank shown in cross-section with three depth levels. At each level, cyan arrows point in all four directions (up, down, left, right) showing fluid pressure acts equally. The arrows get longer at greater depth — shallow has short arrows (low P), mid has medium arrows, deep has long arrows (high P). Footer: P = F/A for solids; P = ρgh for fluids.

Figure 1: Left — same force, different area gives different pressure. Right — fluid pressure increases with depth and acts in all directions.
