Explanation
Pressure is defined as force per unit area and is measured in Pascals in SI units. Greater force or smaller area results in greater pressure. Atmospheric pressure is caused by the weight of air. Water pressure increases with depth. Pressure is important in hydraulics, pneumatics, and many applications. High pressure is used in industries for cutting and shaping materials.
Example
A nail has a sharp point which concentrates force over a small area, creating high pressure that allows it to penetrate wood easily.
Frequently Asked Questions
