In the SI system, because that's the way it is defined. Pressure is defined as force divided by area. SI units are newton / square meter, this derived unit is called the pascal.
This is the way it is defined in the SI, and in some other systems of units. You could just as well create a system of units in which pressure is a base unit, and force is derived (as the product of pressure x area). The decision, which units are base units and which units are derived, is more or less arbitrary.
What else can I help you with?
Is speed a derived quantity?
Velocity is a derived quantity. Speed is velocity without direction. Velocity is derived from distance and time.
Is volume fundamental or derived quantity?
Volume is a derived quantity because it is calculated by multiplying three lengths together in the SI system of units. The SI base units for length are meters, so volume is expressed in cubic meters (m^3). It is not considered a fundamental quantity like length, mass, or time, which are base units in the SI system.
Is voltage a derived quantity?
Whether any quantity is a base quantity or a derived quantity depends on the definitions used in the system of measurements. In the SI, it is a derived quantity, defined as energy per unit charge. In units: joules/coulomb, where both joules and coulombs are also derived units.
What is the difference between a fundamental and derived quantity?
A fundamental quantity is a physical quantity that cannot be defined in terms of other physical quantities, while a derived quantity is a physical quantity that is defined in terms of fundamental quantities through mathematical relationships. Examples of fundamental quantities include mass, length, and time, while examples of derived quantities include velocity, acceleration, and energy.
What is temperature as a derived quantity in terms of length mass and time?
Temperature is a derived quantity that can be expressed in terms of length, mass, and time using the ideal gas law, which relates the pressure, volume, temperature, and universal gas constant of a gas. The ideal gas law equation is PV = nRT, where P is pressure, V is volume, n is the amount of substance, R is the universal gas constant, and T is temperature. Through this equation, temperature can be derived based on the other quantities.
Is area a derived quantity?
Yes, area is a derived quantity.
Definition for fundamental quantities and derived quantities?
the differentiate between fundamental quantity and derived quantity?
What are derived quantities what are the fundamental quantities?
Fundamental quantities are quantities that can be measured such as mass, length and temperature. Derived quantities are quantities that has to be calculated such as pressure, volume and work done.AnswerThe SI does not define 'fundamental quantity', instead it uses the term 'Base Unit'. All other units are 'Derived Units', so-called because they are each derived from combinations of Base Units.
A quantity formed from the combination of other measurements is a what quantity?
derived quantity
Is speed a derived quantity?
Velocity is a derived quantity. Speed is velocity without direction. Velocity is derived from distance and time.
Is cubic feet derived quantities or fundamental quantities?
It is a derived quantity.
Is electric current a basic quantity or a derived quantity?
Current is a basic quantity, measured in amperes.
What is the meaning of derived physical quantity?
The derived quantity is a quantity which has been derived from 2 or more base quantities. Example: Velocity is the rate of change of distance and is written in terms of distance divided by time which are two base quantities.
Is volume a derived quantity?
yes it is,it is derived by cubing the fundamental unit of length
Give the examples on derived and fundamental quantity?
Length is fundamental, area is derived.
Is volume fundamental or derived quantity?
Volume is a derived quantity because it is calculated by multiplying three lengths together in the SI system of units. The SI base units for length are meters, so volume is expressed in cubic meters (m^3). It is not considered a fundamental quantity like length, mass, or time, which are base units in the SI system.
