$(b)$ When is a body said to have uniform velocity ?
$(c)$ How can we describe the position of an object ? Illustrate with suitable example.
$(a)$ Speed is distance travelled per unit time while velocity is displacement per unit time. Speed is always positive while velocity can be zero, negative or positive.
$(b)$ Velocity is said to be uniform, if a body covers equal displacements in equal intervals of time.
$(c)$ The position of an object can be described with respect to an origin or some reference point. Flight of a bird with respect to the earth.
