Chapter 9 : MOTION AND ITS DESCRIPTION

INTEXT QUESTIONS 9.1

Choose the correct answer in the followings:

1. For an object moving along a straight line without changing its direction the

(a) distance travelled > displacement

(b) distance travelled < displacement

(c) distance travelled = displacement

(d) distance is not zero but displacement is zero.

Answer: (c) distance travelled = displacement

[ When an object moves along a straight line without changing direction, the path length (distance) and the straight-line distance from start to finish (displacement) are the same. Displacement only differs from distance if the object changes direction or returns to its starting point. ]

 

2. In a circular motion the distance travelled is

(a) always > displacement

(b) always < displacements

(c) always = displacement

(d) zero when displacement is zero

Answer: (a) always > displacement

[ In circular motion, the distance travelled is the actual length of the curved path, while displacement is the shortest straight-line distance between the starting and ending positions.]
