Prove that average velocity of an object can never be greater than the average speed of an object over a given interval of time.

A : The magntidue of average velocity in an interval can never be greater than average speed in that interval. R : For a moving object distance traveled ge"|Displacement|"

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.

An object travels 20 m in 10 s. What is the average speed of the object ?

Can the displacement be greater than the distance travelled by an object ? Given reason.

Assertion: The magnitude of average velocity of the object over an interval of time is either smaller than or equal to the average speed of the object over the same interval. Reason: Path length (distance) is either equal or greater than the magnitude of displacement.

Show that avertage velocity of the object over an interval of time is either smaller than or equal to the average speed of the object over the same interval.

It magnitude of average speed and average velocity over an interval of time are same, then
