Velocity is Vector quantity while speed is a scalar quantity.

speed is distance per unit time whearas velocity is displacement per unit time....
speed is scalar quantity and has no direction but velocity is vector and has direction...
eg...
if a body is performing uniform circular motion of radius R then after complete rotation particle comes to the same point so distance becomes 2pieR but displacement becomes 0..
so speed = 2pieR/T and velocity =0
from dis it can be said that velocity may be 0 but speed can never be 0...

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
