Draw the $x \to t $ graphs which represent the positive, negative and zero velocity
Draw the $x \to t $ graphs which represent the positive, negative and zero velocity
In graph
$(a)$, the position increases with respect to time, hence the average velocity is positive. In graph
$(b)$, the position decreases with respect to time, hence the average velocity is negative. In graph
$(c)$, the position doesn't change with respect to time, hence the average velocity is zero.
