Difference between force and pressure

Posted By: Sm Adminon: December 07, 2015In: Miscellaneous

Force:
Force is the push or pulls which leads to change the motion of an object. Force is said to be a vector quantity which has both the magnitude and direction. The SI unit of the Force is Newton and is represented by the symbol F. The formula of the Force is: Force = Mass * Acceleration.
Pressure:
Pressure is the amount of the force acting per unit area. Symbolically, the pressure is written as p or P. Pressure is said to be a scalar quantity which has only magnitude, not direction. The SI unit of pressure is Pascal which is also called Newton per square meter. Mathematically, P = F/A.
Differences:

Basis	Force	Pressure
Definition (www.oxforddictionaries.com)	Strength or energy as an attribute of physical action or movement.	Continuous physical force exerted on or against an object by something in contact with it.
Synonyms	Effort, strength and violence	Tension, strength, burden, squeeze, strain and stress.
Antonyms	Passivity	Relaxation
Pronunciation	Eng (UK): / fɔːs/ Eng (US): / fôrs/	Eng (UK): / ˈprɛʃə/ Eng (US): / ˈpreSHər/
Types	Two types of forces are: Contact force Frictional force Tension force Normal force Air resistance force Applied force Spring force Action-at-a-Distance forces Gravitational force Electrical force Magnetic force	Types of pressure are: Fluid pressure Negative pressure Stagnation pressure Surface pressure and surface tension Pressure of an ideal gas Vapor pressure Liquid pressure Kinematic pressure
Word origin	The word force was originated on 1250-1300 (14th century) from Middle English.	The word pressure was originated on 1350-1400 (14th century) from Middle English.
Sub categories	It has sub categories: normal, gravity and applied forces.	It has no sub-categories.
SI unit	Its SI unit is Newton.	Its SI unit is Pascal.
Formula	F = m*a	P = F/A
Velocity	Force if applied from one direction can change the object’s velocity.	Pressure does not change the velocity of the object.
Quantity	Force is vector quantity which depends upon the both magnitude and direction.	Pressure is a scalar quantity which depends upon magnitude only.
Instrument of measurement	Instrument of measurement is a dynamometer.	Instrument of measurement is a Manometer.
Example in Sentence	I must use the force to open that stucked window. Arjun applied force in most of his stunts.	Though she was not interested, her parents are putting a lot of pressure on her to get married. The normal human blood pressure is below 120 and over 80 (120/80).
