sinjan.j

In my text book it says that,"Some quantities in physics are regarded fundamental in that they are obtatained by the most basic measurements,that can be devised."

can u explain what the highlighed part means in simple language?

it seems to be very confusing for me.

HI, FUNDAMENTAL QUANTITES LIKE METRE, ETC ARE FUNDAMENTAL BECAUSE THEY CAN BE DEFINED/DEVISED SIMPLY LIKE A PARTICULAR LENGTH OFA ROD IS TAKEN AND DECIDED THAT IT IS 1 METRE. aND LIKE THIS . OTHER QUANTITES LIKE VELOCITY RELY ON THESE FUNDAMENTAL QUANTITIES AND HENCE R CALLED DERIVED QUANTITIES

. RATE ME IF IT HELPS!!!!!!!!!!!!!!

fundamental quantities r d most basic quantities...which cannot be further resolved in terms of other simpler quantities.....length,mass,time,current,amt of substance r d egs...
