Pressure
Definition
Pressure refers to the force applied per unit area. It measures how much force is distributed over a given surface area.
Analogy
Think about stepping on sand with bare feet versus stepping on it with shoes. When you step with shoes, your weight is spread out over a larger area, reducing pressure. But when you step without shoes, all your weight is concentrated on a smaller area, increasing pressure.
