La presión

The video tutorial explores the concept of pressure, emphasizing its significance in physics. It begins by introducing pressure and its role in everyday life, using examples like stomping and cutting. The tutorial explains how pressure is affected by surface area and provides a mathematical definition, introducing units like Pascal. It discusses atmospheric pressure, its effects, and how it varies with altitude and depth. The video concludes with an explanation of pressure in fluids and methods to measure it, such as using a pressure gauge or mercury column.
