Can the displacement be greater than he distance travelled by an object?

Give one example where the displacement is zero but the distance travelled is not zero.

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.

_________ is the distance travelled by a body per unit time.

Distance travelled by a body in a given time

The set of all numbers greater than 0 is an ……..interval

Define displacement and distance.
