Welcome :-D

Rectilinear motion [straight path]

--> distance and displacement are equal.

--> speed and velocity are also equal.

Note-1

--> In a straight line motion the ratio of distance by displacement is equal to 1.

--> In a straight line motion the ratio of speed and velocity is equal to 1.

Note-2

In gernal: [covered path]

     Distance

--> ------------------------ = >1

    Displacement

      Displacement

--> -------------------------------- = <1

         Distance

      speed

--> ------------------- = >1

      Velocity

       Velocity

--> ----------------------- = <1

        Speed

Average speed

--> It is defined as the ratio of total distance    taken by an object.

                                                   --------------------------- ,

                                                      Total time

--> Average speed= total distance

                                  ---------------------------

                                     Total time

Average velocity

--> average velocity= total displacement

                                 -------------------------------------

                                         Total time

Converting km/h to m/s

--> 1km         1000m           5

   ----------   = ---------------   =   ----- m/s

     1h            3600s           18

--> 2kmph = 2×5/18 m/s

_______________________

--> 1kmph = 5/18 m/s

--> 1m/s = 18/5 kmph

----------------------------------------

See you in part-4 bye :wave:
