When to use velocity=displacement/time and velocity=s/t? I mean, whats the main difference? please explain clearly?

Question

anonymous · Answer

its the very same thing 
s stands for displacement 
whereas t stands for time

anonymous · Answer

@paarth - s stands for distance, and displacement and distance are different! one is vector while the other is a scaler quantity.

@jahanvi as far as i know, and i think i know correctly, s is the symbol for displacement

anonymous · Answer

well, lets see..

anonymous · Answer

speed= distance/time
distance is the  total length of the motion 
displacement is the final position minus the initial position
velocity= displacement/time
