Velocity is a derived quantity. Speed is velocity without direction. Velocity is derived from distance and time.
No, speed is scalar - it has only one value which is magnitude. The vector is velocity, which contains speed and direction.
It may help to know that a vector is a specific speed in a specific direction. Example, 18kph at North Azimuth 84 degrees.
True
Velocity is a derived quantity. Speed is velocity without direction. Velocity is derived from distance and time.
Fundamental quantity
Volume is derived, from length.
speed is a scalar 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.
Velocity is a derived quantity. Speed is velocity without direction. Velocity is derived from distance and time.
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.
Yes, area is a derived quantity.
This is not at all unusual. Volume for instance is formed from length, width, and depth. Electrical power is formed from knowing voltage and current. Speed from distance and time. There are many examples easy to think of.
the differentiate between fundamental quantity and derived quantity?
derived quantity
Fundamental quantity
Volume is derived, from length.
It is a derived quantity.
Current is a basic quantity, measured in amperes.
speed is a scalar 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.
