Question

I'm gonna need at least 3 points of difference between distance and displacement.

Answer 1

Three differences are: 

(i) Distance is the length of the actual path taken by a particle while displacement is the length of the shortest path between the initial and final position of the object.
(ii) Distance is a scalar quantity while displacement is a vector quantity.
(iii) Distance can never be negative but displacement can be negative.

Answer 2

Distance                                                       Displacement

Distance is the measurement            Displacement is the shortest distance
of total area covered                          covered by the object
by an object.  

It is a scalar quantity.                           It is a vector quantity.

Distance = speed/time                         Displacement = velocity*time

It is denoted by d.                                It is denoted by s.
