What does the SI unit for speed, m/s, stand for?
The International System of Units (SI) has two type of units, base units and derived units. Speed is a derived unit. Its unit is Meter/sec. Its a scalar quantity.
Is the unit of speed a basic unit or a derived unit?
It is a derived unit. It measure distance traveled per unit of time. For example meter per second or m/s. Speed or velocity as it is sometimes called is derived from the units for distance and time.
Why are derived units more complex than fundamental units?
Derived units is obtained from a combination of fundamental units. Derived unit is a cubic centimeter or a cube that is a centimeter on each side.
What is the difference between a base unit from a derived unit?
There are 7 base SI units and all other are defined using these 7 base units. See the related question below:[http://wiki.answers.com/Q/What_are_all_the_SI_unitsWhat are all SI units?]
What is a derived untit?
It means that it is defined on the basis of other units. For example, in the SI, the meter and the second are two of the seven "base units"; the unit for area is the square meter (meter x meter), so it is a DERIVED unit; so is the unit for speed, meters / second.
Is velocity a derived unit?
No, velocity is not a derived unit. It is a fundamental physical quantity that measures the rate of change of an object's position with respect to time. Velocity is derived from the fundamental units of length and time.
Why the unit of density is called derived unit?
Density is not a derived unit.. It is a physical quantity and hence is a derived quantity.. the unit of density kgm-3 or gcm-3 is a derived unit because it can be expressed as the quotient of base units. In general, a unit is said to be derived if it can be expressed as the product and/or quotient of base units.
What does the SI unit for speed, m/s, stand for?
The International System of Units (SI) has two type of units, base units and derived units. Speed is a derived unit. Its unit is Meter/sec. Its a scalar quantity.
Why is pressure a derived quantity?
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.
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 quantity symbol of length?
The quantity symbol for length is "L." In the International System of Units (SI), the standard unit of length is the meter, represented by the symbol "m." Length can also be measured in various other units such as kilometers, centimeters, and millimeters, but the fundamental symbol remains "L."
Is the unit of speed a basic unit or a derived unit?
It is a derived unit. It measure distance traveled per unit of time. For example meter per second or m/s. Speed or velocity as it is sometimes called is derived from the units for distance and time.
What is the base unit of voltage?
The base unit of voltage is the volt, a combined unit meaning joules per coulomb.AnswerThe SI unit for voltage is the volt (symbol: V), which is a derived unit -not a base unit. There are seven base units in the SI system: metre, kilogram, second, ampere, candela, kelvin, and mole. SI units which are not base units are termed 'derived units'.
What is the SI unit for quantity of radioactive materials?
The SI unit for quantity of radioactive materials is Becquerel.The becquerel (symbol Bq) is the SI-derived unit of radioactivity.One Bq is defined as the activity of a quantity of radioactive material in which one nucleus decays per second.
What is magnetic flux measured in?
The SI unit of magnetic flux is the weber (in derived units: volt-seconds)
Can a quantity have unit and still be diamensionless?
No, a quantity cannot have units and still be dimensionless. The dimensions of a quantity are determined by its units, so if a quantity has units, it has dimensions. Dimensionless quantities are those without any units.
Is the unit for force a base unit or a derived unit?
The unit for force, the newton (N), is a derived unit in the International System of Units (SI). It is derived from the base units of mass, length, and time.
