Is displacement a scalar quantity ?


A body is moving along a circular path of radius R. What will be the distance travelled and displacement of the body when it completes half a revolution ?


A body travels a distance of 3 km towards East, then 4 km towards North and finally 9 km towards East.

What is the resultant displacement ?


A body is moving in a straight line and its displacement at various instants of time is given in the following table 

Time (s) 0 1 2 3 4 5 6 7
Displacement (m) 2 6 12 12 12 18 22 24

Plot the displacement-time graph and calculate

(i) Total distance travelled in the interval 1 s to 5 s.

(ii) Average velocity in time interval 1 s to 5 s.


Define Displacement.


A car covers 90 km in `1 1/2` hours towards east. Calculate

  1. displacement of car,
  2. its velocity in (a) kmh−1 (b) ms−1.

Can you suggest the kind of motion of a body from the following distance – time graph?


An object is dropped from rest at a height of 150 m and simultaneously another object is dropped from rest at a height of 100 m. What is the difference in their heights after 2s if both the objects drop with the same accelerations? How does the difference in heights vary with time?


Using the following data, draw time - displacement graph for a moving object:

Time (s) 0 2 4 6 8 10 12 14 16
Displacement (m) 0 2 4 4 4 6 4 2 0

Use this graph to find average velocity for the first 4 s, for the next 4 s and for the last 6 s.


A body is projected up with an initial velocity of u m/s. It goes up to a height, ‘h’ meters in seconds' time. Then it comes back at the point of projection.
