An object has moved through a distance. Can it have zero displacement? If yes, support your answer with an example.

Yes, if object has moved through a distance, it surely can has zero displacement. as displacement is a vector quantity depending on starting and ending position not on the path.

For example, 1 circle of motion has distance 2πR but 0 displacement.

Explanation:

Yes, zero displacement is possible if an object has moved through a distance.

Suppose a ball starts moving from point A and it returns back at same point A, then the distance will be equal to 20 meters while displacement will be zero.

half of a circle

explanation:

the arrow and the top of the circle is matching together. it is not a polygon because a polygon would always be the same shape. therefore, an half of a circle is called semicircle so you would find the radius of it.
