V-e-l-o-c-I-t-y:v-e-l-o-c-i-t-y is the rate of change of displacement,i.e.,displacement per unit time.
                                  v=ds/dt
its SI unit is m/sec
A-c-c-e-l-e-r-a-t-i-o-n:a-c-c-e-r-e-l-a-t-i-o-n is rate of change in velocity.
                                  a=dv/dt
its SI unit is m/(sec^2)
D-i-s-p-l-a-c-e-m-e-n-t:the shortest distance or distance between two specified points,i.e.,from initial point to final point is called d-i-s-p-l-a-c-e-m-e-n-t.
its SI unit is m
D-i-s-t-a-n-c-e:the path of an object is called d-i-s-t-a-n-c-e.
its SI unit is m
R-e-t-a-r-d-a-t-i-o-n:negative acceleration is r-e-t-a-r-d-a-t-i-o-n or d-e-c-e-l-e-r-a-t-i-o-n.
its SI unit is m/(sec)^2
