What is the example of displacement being negative ?   
Asked by harshilmodi74.tl | 16 Apr, 2020, 11:53: AM

Displacement is a vector quantity.
It can be negative, positive and zero. Displacement is quantity which considers magnitude as well as direction. 
If you move in forward direction with reference to your reference point ( initial position) then the displacement will be positive and if you move in backward direction with reference to the initial positin then the displacement is negative. 
 
Let's take one example: - 
 
C.......................A.......................B 
 
If you walk 5 metres from A to B i.e. to the right hand side then the displacement will be +5 m (here '+' sign indicates that you have moved to the right hand side)
If you walk 5 metres from A to C i.e. to the left hand side then the displacement will be - 5 m (here '-' sign indicates that you have moved to the left hand side) 
 
So, positive and negative signs along with the magnitude indicates the direction of displacement (vector quantity).
