Q.
The position-time graph for a particle moving along a straight line is shown in figure. The total distance travelled by it in time $t=0$ to $t=10\, s$ is
Motion in a Straight Line
Solution:
The total distance travelled from 0 to $2\, s$ is $10\, m$
$2\, s$ to $8\, s \rightarrow$ Zero distance
and from $8\, s$ to $10\, s \rightarrow 10\, m$
So, distance $=10+0+10=20\, m$
