What is difference between base quantity and derived quantity?

Answer 1

Base quantities (Scalar Quantities) :

Independent quantities who have single standard units.

- time /seconds

-distance/meters

Derived Quantities (Vector Quantities):

Quantities derived by multiplying or dividing 2 base quantities.

- Velocity = distance/time

unit of Velocity = m/s

Answer 2

length, mass, time, eclectic current, temperature, intensity of light and amount of substance are example of base quantity. Derived quantity; the quantity that are expressed in term of base quantity are called derived quantity.

Answer 3

Base quantities are fundamental physical quantities that cannot be defined in terms of other physical quantities. They are independent and form the foundation of the International System of Units (SI). Derived quantities, on the other hand, are physical quantities that are derived from base quantities through mathematical relationships or formulas. They depend on one or more base quantities for their definition and measurement.

Answer 4

Alright, buckle up, honey. Base quantities are the fundamental physical quantities that are independent of other quantities, like time and mass. Derived quantities, on the other hand, are derived from combinations of base quantities, like velocity or acceleration. So, in simpler terms, base quantities are the OGs, while derived quantities are their offspring. Hope that clears things up for ya!

Answer 5

Base quantities are fundamental physical quantities that are not defined in terms of other quantities, such as length, mass, time, electric current, temperature, amount of substance, and luminous intensity. Derived quantities are physical quantities that are defined in terms of base quantities, such as velocity (defined as distance divided by time) or acceleration (defined as velocity divided by time).

Answer 6

I think basic quantity or fundamental quantity are quantities that can be measured using measuring instruments. Ex. Length is measured by a ruler. Time is measured by a timewatch. Mass is measured by platform balance etc. Derived quantity are quantities that is a combination of both fundamental and derived. It uses formulas. Ex Area is square meter. Volume is cubic meter. Force is F= ma etc.

Answer 7

A fundamental quantity is something like length, mass or time. A derived quantity is something you get from combining fundamental measurements, like speed (comes from distance and time) or density (comes from mass and volume). The terms 'fundamental quantities' and 'derived quantaties' most likely refer to the units used, so in standard units, the fundamental quantities are the meter, kilogram, second and Ampere. There are heaps of derived quantities.

Answer 8

A "derived" quantity is derived from some other quantity. Since you have to start somewhere, SOME quantities must be defined first; these are the fundamental quantities, and others are derived from them. It is a more or less arbitrary decision which quantities are DEFINED as fundamental; as an example, take the standard formula for speed:distance = speed x time

If you define any two of these quantities, you can then derive the third one with this formula. It is an arbitrary decision which of these quantities are defined as fundamental - for example, some of them may be chosen as fundamental because they are easier to measure.

Here is another example: Using the fact that the area of a square is the square of the length of the side, you can define length as a fundamental quantity, and then define area as length squared; but you can just as well define area as a fundamental quantity, and then define length as the square root of an area. Since it is generally easier to measure a length, the first route is taken in many measurement systems, including the SI.

Answer 9

A fundamental quantity is a measurement of one of the following characteristics:

• mass,
• length
• luminous intensity
• time
• electric current
• temperature
• amount of a substance.
  

The measurement of other characteristics may be calculated on the bases of one or more of these: for example, volume = length^3, density = mass/volume and so on.

It is possible to replace some of these fundamental units by others which are "natural" units. In the above scheme, speed = distance/time, an alternative is distance = speed*time. It is, therefore, possible to use the speed of light (a natural constant) as a fundamental unit and distance as a derived unit.
