what is difference between distance and displacement?

Answer to first question is as follow:-

Following are the four differences between distance and displacement.

 

Distance
Displacement
1.
It is the length of the total path covered by the body.
1.
It is the shortest distance between the final and the initial point.
2.
It only has magnitude, doesn’t have direction (scalar quantity).
2.
It has magnitude as well as direction (vector quantity).
3.
Distance travelled is non zero whenever there is a linear motion.
3.
Displacement is zero if the body comes back to its initial position.
4.
Distance measured is always positive.
4.
Displacement can be positive or negative depending on the reference point.

Distance is the path covered by a moving body. Displacement is the SHORTEST path that the body covers. 
Distance can never be 0 (except at rest) or decrease . Displacement can be 0.
