Q3 of 58 Page 36

Assertion: Displacement of a body may be zero when distance travelled by it is not zero.
Reason: The displacement is the shortest distance between initial and final position.

Assertion: The accelerated motion of an object may be due to change in magnitude of velocity or direction or both of them.

Reason: Acceleration can be produced only by ca hange in magnitude of the velocity it does not depend on the direction.

Assertion: The Speedometer of a car or a motor-cycle measures the average speed of it.

Reason: Average velocity is equal to total displacement divided by the total time taken.
