Pressure and Atmospheric Pressure

The video tutorial explains the concept of pressure using relatable examples such as swings, nails, and balloons. It covers how pressure is defined as force per unit area and its applications in everyday objects like backpacks and nails. The tutorial also discusses pressure in liquids and gases, explaining phenomena like water levels in containers and atmospheric pressure. The importance of pressure in designing objects and managing waste is highlighted, along with practical examples like dams and diving suits.
