Scalar and Vector Quantities

Scalar quantities-Has magnitude only

Vector quantities- has magnitude & direction

1.Distance and displacement

Distance is the total length covered by a moving object without taj=king into consideration the direction in which the body is moving.

Displacement is the distance moved along a straight line in a specified direction.

example:
2 boys walked from a point A to point B.
Distance between the 2 points depends on the path chosen to travel between the 2 points.There may be an infinite number of paths.However,there is only 1 displacement between 2 points.It is along a straight line joining the starting and finishing points.It is the shortest possible route from A to B

NOTE: This has been a very short tutorial compared to what i plan to give all my 'fans' if this blog turns out to be popular.I shall continue with the whole syllabus if i get a good response!!!
