Length, mass, and time are chosen as base quantities in mechanics because they are fundamental and independent of each other. By having these three base quantities, all other physical quantities in mechanics can be derived from them through a combination of multiplication and division. This simplifies the understanding and analysis of physical systems.
What else can I help you with?
How can you differentiate between base and derived quantities?
Base quantities are independent and cannot be expressed in terms of other quantities, while derived quantities are dependent and derived from combinations of base quantities. Base quantities are fundamental in a system of measurement, while derived quantities are derived through mathematical relationships. For example, length is a base quantity, while speed is a derived quantity that depends on both length and time.
What are the examples of base quantities and derived quantities?
Examples of base quantities include length, mass, time, electric current, temperature, amount of substance, and luminous intensity. Derived quantities are those that are defined in terms of base quantities, such as velocity (length/time), acceleration (length/time^2), force (mass * acceleration), and energy (mass * (length^2/time^2)).
Why are area and speed derived quantities?
Area and speed are derived quantities because they are obtained by combining base quantities. Area is derived from multiplying two length measurements, while speed is derived from dividing a length measurement by a time measurement. These derived quantities are built upon the fundamental base quantities of length and time.
What is derive quantities with explanation?
A derived quantity is one that is derived from others. For example, the meter is the official unit of length; since area can be defined as a length squared, that's exactly how the area is defined in the SI, i.e., it is measured in square meters. Similarly, a speed is measured in meters/second (both meters and seconds are defined as base quantities).
What are base quantities and derived quantities?
Base quantities are fundamental physical quantities that cannot be defined in terms of other physical quantities. They are used as building blocks in expressing other physical quantities. Derived quantities, on the other hand, are physical quantities that are derived from combinations of base quantities through multiplication and division with or without other derived quantities.

How area is derived from base quantities?
Area is length x length, or length squared.

Is volume a base quantity?
No, volume is not a base quantity; it is a derived quantity. Base quantities, such as length, mass, time, electric current, temperature, amount of substance, and luminous intensity, are the fundamental physical quantities from which other quantities are derived. Volume is calculated from base quantities, specifically length, as it is expressed in cubic units (e.g., cubic meters).

What is difference between base quantity and derived quantity?
Base quantities (Scalar Quantities) :Independent quantities who have single standard units.- time /seconds-distance/metersDerived Quantities (Vector Quantities):Quantities derived by multiplying or dividing 2 base quantities.- Velocity = distance/timeunit of Velocity = m/s
How many base quantitien are there?
There are seven base quantities in the International System of Units (SI). These base quantities are: length (meter), mass (kilogram), time (second), electric current (ampere), thermodynamic temperature (kelvin), amount of substance (mole), and luminous intensity (candela). Each base quantity is defined by a specific physical phenomenon and serves as the foundation for deriving other physical quantities.
What is difference between base quantities and derived quantities?
Basic or fundamental quantities are seven in number. They cannot be derived right from one another. Hence they are independent. They are length, mass, time, electric current, temperature, quantity of substance, luminosity. Two sub are there. They are plane angle and solid angle. But derived are many in number. Just by the name they are derived right from the fundamental. They are area, volume, velocity, acceleration, force, momentum, magnetic induction, electric field, dipole moment, pressure, density etc etc
