$(a)$ Calculate the magnitude of displacement of the truck in $15$ seconds.
$(b)$ During which part of the journey was the truck decelerating ?
$(c)$ Calculate the magnitude of average velocity of the truck.
Can you suggest about the kind of motion of a body from following distance$-$time graphs ?
A body is moving along a circular path of radius $R$. Find the displacement of the body when it completes half a revolution.
What does the odometer of an automobile measures ? Which of the following is moving faster ? Justify your answer.
$(i)$ A scooter moving with a speed of $300\, m$ per minute.
$(ii)$ A car moving with a speed of $36 \,km$ per hour.
Distinguish between terms distance and displacement.
