Question

7. A particle starts from the origin, goes along the X-axis up to the point(20m,0) and then returns along the same line to the point(-20m,0). Find the distance and displacement of the particle during the trip.
​

Answer 1

$\sf{distance = 20 - ( - 20)}$

$\orange{ \therefore \sf{distance = 40 \: m}}$

$\sf{ \purple{and : }}$

$\orange{ \sf{displacement = 20 \: m}}$

$\sf{ \purple{additional \: information : }}$

$\sf{1)displacement \: is \: shortest \: distance} \\ \sf{between \: two \: points.}$

$\sf{ 2)while \: distance \: is \: total \: path \: you \: }\\ \sf{travelled.}$
