Best ResponseYou've already chosen the best response.0Ok so there are two types of units: 1) Basic (given above by ashna) 2) Derived for example: speed = distance /time unit of distance = metre and unit of time = second hence unit of speed = m/s

Best ResponseYou've already chosen the best response.0how? i hav nt under stood it

ashna

Best ResponseYou've already chosen the best response.3okay , displacement = distance = L (length) divided by time (t)

Best ResponseYou've already chosen the best response.0okay why u have taken distance=L

ashna

Best ResponseYou've already chosen the best response.3distance is nothing but length .

ashna

Best ResponseYou've already chosen the best response.3distance travelled , is the length travelled understood ?

ashna

Best ResponseYou've already chosen the best response.3where displacement is just the other word for distance , displacement is the shortest dist travelled and distance is the longest possible distance = L (length)

Best ResponseYou've already chosen the best response.0Dimension of a body is determined by the coordinate axis attach to it. There are 1D, 2D, 3D and 4D(It includes Time).The existence of 4D is beyond our imagination.
