Pressure is the amount of force being pushed on or between two different things. Everything and everyone on earth experiences the effects of pressure. It also affects many different things in the world, from health and wellness to physics and how the world works, it truly is a vast concept.
The standard unit of pressure in the International System of Units (SI) is the Pascal (Pa). A single Pascal is equal to one Newton per square meter. There are other units you can use to measure pressure, but Pascal is the widely used one.
There are 4 types of pressure:
Absolute pressure is the pressure measured relative to a perfect vacuum, or somewhere there is zero pressure. Gauge pressure is relative to the surrounding atmospheric pressure, where the value can be positive or negative depending if its value is higher or lower than the atmospheric pressure.
The larger the area that force is applied to, the lower the pressure. If the area where force is applied to is smaller, then pressure will be higher. Think of a knife, if it has a sharp edge it is thinner and applies more pressure to a smaller area making it cut better, if the knife is dull it is making contact to a larger area providing less pressure and less cutting capabilities.
No, pressure requires force to be applied to a certain area. Pressure arises from the interaction of particles that occurs due to force being applied to an area.
