When is the magnitude of displacement equal to the distance?
A train takes 3 h to travel from Agra to Delhi with a uniform speed of 65 km h-1. Find the distance between the two cities.
How is the distance related with time for motion under uniform acceleration such as the motion of a freely falling body?
Calculate the distance and displacement in the following case:
A body is moving along a circular path of radius r. What will be the distance and displacement of the body when it completes:
`(3/4)` th of a revolution

Exercise Problems.
An athlete completes one round of a circular track of diameter 200 m in 40 s. What will be the distance covered and the displacement at the end of 2 m and 20 s?
The displacement is zero when the initial and final positions are ______.
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?
