Pressure is discussed in the video, with examples and the formula defined, showing how it can be adjusted and applied in various scenarios like hydraulic systems. Liquid pressure is also explained, demonstrated through an experiment with two glass tubes filled with water, highlighting its relevance in everyday applications.
Insights
- Pressure, as discussed by the speaker, is determined by the amount supplied, the surface area of the object, and the merit of the foot, and is calculated using the formula thrust upon area with the unit being Newton per square meter.
- Liquid pressure, exemplified through an experiment with two glass tubes and water, is a result of the weight of the liquid in a container, and hydraulic systems utilize this principle to transmit pressure through liquids for tasks such as lifting vehicles.
