Question

S.I unit of displacement is ?

Answer 1

Hint:Recall the two measurement systems: S.I and C.G.S. The displacement is the distance between the two points. The S.I unit of displacement is greater than its C.G.S unit that is centimeter.

Complete answer:
We know that there are two measurement systems: the S.I unit system and C.G.S unit system. We know that the displacement is the distance between the two points. S.I unit of displacement is meter. Also, the C.G.S unit of displacement is centimeter. Therefore, we can see that the C.G.S unit is a comparatively smaller unit of measurement.

S.I unit of displacement is meter.

Additional information:
The S.I unit system is the International System of units and widely used throughout the world in most of the countries. It has seven basic units of measurement: second, meter, kilogram, ampere, Kelvin, mole and candela. Second is the S.I unit of time, kilogram is the S.I unit of mass, ampere is the S.I unit of current, Kelvin is the S.I unit of temperature, mole is the S.I unit of the number of molecules, and candela is the S.I unit of luminosity. The other measurement unit system is C.G.S unit system abbreviation of centimeter-gram-second. These three are the basic units of the C.G.S measurement system.We always prefer the S.I unit to express the measurement of physical quantities.

Note: Students should understand the difference between S.I unit and C.G.S unit. One can easily tell the C.G.S unit of displacement since it is an abbreviation of centimeter-gram-second but remembering S.I units of the physical quantities is often more tricky than C.G.S units. If you don’t remember the S.I unit of a physical quantity, you can recall the formula for it.
