In your everyday life,you come across a range of motions in which
$(a)$ acceleration is in the direction of motion.
$(b)$ acceleration is against the direction of motion.
$(c)$ acceleration is uniform.
$(d)$ acceleration is non$-$uniform.
Can you identify one example each of the above type of motion?

(N/A) When the speed of a car on a road increases,the acceleration of the car is in the direction of motion.
$(b)$ When brakes are applied to a car in motion,its speed decreases. The acceleration produced in the car is against the direction of motion.
$(c)$ When a body is falling freely under the action of gravity,it has a uniform acceleration $g = 9.8 \ m \ s^{-2}$.
$(d)$ When a car is passing through city traffic,its acceleration or retardation is non$-$uniform depending on the volume of traffic.
