Assertion : On a curved path, average speed of a particle can never be equal to average velocity. Reason : Average speed is total distance travelled divided by total time. Whereas average velocity is, final velocity plus initial velocity divided by two.

Assertion : The speedometer of an automobile measure the average speed of the automobile. Reason : Average velocity is equal to total displacement per total time taken.

When is the average speed of an object equal to the magnitude of its average velocity ? Give reason also.

Assertion : The average speed of an object is greater than or equal to the magnitude of the average velocity over a given time interval. Reason : The two are equal only if the path length is equal to the magnitude of displacement.
