Air Pressure

Example:

Imagine you're at a crowded concert, trying to move through a dense crowd to reach the front. Just as each person in the crowd is exerting a force against you, making it difficult to move, air pressure is the weight of air molecules pressing down on a surface. In both situations, the force exerted by each individual (whether a person or an air molecule) accumulates to create significant pressure, making it challenging to move forward or, in the case of air pressure, to lift against it.
