a particle starts from the origin goes along the x axis to the point 20m,0m and then returns the point -20m,0m along the x axis .the distance and the displacement of the particle during the trip is
Answers
Total Distance is the total lenth of the whole path covered by the particle.
Total Distance = 20+20 = 40m
Total Displacement is the length between the final and initial positions of the body only.
Total Displacement = -20m
(negative sign because the direction of displacement is opposite of x axis, and we have taken x axis as the positive direction)

Answer:
Distance : 60m
Displacement : -20m
Explanation:
Distance :
a) From Origin, O = (0,0) to let's say point A = (20,0)
So, the particle first travels a distance of 20m along the x axis starting from the origin.
b) From point A = (20,0) to let's say point B = (-20,0)
So now, the particle covered a distance of 40m along the x axis i.e. from A to O (20m) and from O to B (20m)
Therefore, the Total Distance = (20m + 40m) = 60m
Displacement :
Since displacement is the minimum distance between the final and the initial position of the body,
The distance covered by the particle from O to A and A to O won't be included.
So, the displacement would be the distance covered from O to B i.e. - 20m
