what is force and pressure
Answers
Force is a push or pull which an object experience when it interacts with another object.
The perpendicular force (thrust) acting per unit area of the surface.
Explanation:
What is a Force?
A force is the push or pulls upon an object. It results from the object’s interaction with another object. Whenever there is some interaction between the objects, then there will be a force upon each of the objects. So, in lack of interaction, objects no longer experience the force. It is a vector quantity and hence has a specific direction of action with the magnitude. Therefore for a complete description, we have to describe both the magnitude and the direction. Due to being vector quantity, in diagrams force is represented by an arrow. SI unit of force is Newton or kg meter per second square.
What is Pressure?
The pressure is the physical force applied on an object in the perpendicular direction to the surface on its unit area. Its basic formula is dividing the force by the area of the surface. Its unit of measurement is Pascal (Pa). Pressure exists in various forms in nature and our surroundings. The main types of pressures are Absolute, Atmospheric, Differential, and Gauge Pressure.
In our daily life, we may easily find many phenomena that are related to pressure. For example, while sipping beverages from a straw, we actually suck the air out of the straw. And while we sip the beverage, we are actually applying the pressure. The SI unit for pressure is the pascal or Newton per square meter. Some other units are also there like pounds per square inch and bar etc.
