Q. A body is moving along a straight line path with constant velocity. At an instant of time the distance travelled by it is S and its displacement is D, then
A) D$\ < \ $S
B) $D > S$
C) $D = S$
D) $D \leq S$
Explanation
(c) A body is moving on a straight line with constant velocity. Between $A$ and $B$, the straight line is the shortest distance. This is the distance travelled. The particle starts at $A$ and reaches $B$ along the straight line. Therefore displacement is also $AB,\ D = S$
