When you step outside on a sunny day or gaze up at the clear blue sky, have you ever wondered about the invisible force that surrounds us, shaping our environment and affecting our daily lives? This force is none other than atmospheric pressure. Atmospheric pressure is a fundamental concept in physics and meteorology, and it plays a crucial role in our understanding of the world around us. In this blog post, we will delve into the fascinating world of atmospheric pressure, exploring its units, measurement techniques, its impact on us, and the importance of physics tuition in grasping this fundamental concept. What is Atmospheric Pressure? Atmospheric pressure, also known as air pressure, is the force exerted by the weight of the air above a specific point on the Earth's surface. This force is responsible for maintaining the Earth's atmosphere and making it possible for us to breathe. In simple terms, atmospheric pressure is the weight of the air pressing down on everything on
