Examples of physical quantities are mass,volume, length, time,temperature,electric current.
that's all thank you
Those quantities which cannot be derived from any other such as length, mass, time, temperature, electric current, light luminosity are examples for fundamental physical quantities.
physical quantities have numerical magnitude and unit
efficiancy in physics is always measured as ratio of output and input
Physics, Astronomy, Chemistry, Geology, and Oceanology.
Scalars and Vectors quantities
The smallest change in a measured physical quantity that an instrument is capable of detecting.
In the SI standard for physics units (see NIST website,) quantities of electricity are measured in coulombs, same as the quantity of electric charge.
importance of physics in home
velocity is a measure of how fast an object is traveling through space in a discrete amount of time, tranquility in the other hand can measure how long an object is at a particular place in space all of these quantities can be measured in a physics laboratory; so yes tranquility as the inverse of velocity is a physical quantity.
# Units allows use to compare quatities that are not in the same space, place or time # units also indicates the physics quantities measured or been measure as each quantities has particlar units
Length, mass, and time are the three fundamental dimensions on which the measurement of all physical quantities is dependent.
Experiment. Experiments involving measurement of the number of multiples of the base units in each of the ways reality can be measured. That is why physics is called the quantitative science, the science of quantities where a quantity is a numerical value multiplied by units of measurement.
