Numericals on Distance and Displacement

1. A man moves from point A to point B then to point C and finally to point D as shown in

the diagram. Find the distance and displacement travelled by the man.

2. An object moves from point A to point B to point C, then back to point B along the line

shown in the figure below. Find the distance covered by the moving object and the

displacement of the object.

Answer 1

Explanation:

when a body covering any distance or changing it place or performing any action than that body is considered as in motion.when a body just remain on it place than rest
