Question
A bird sitting on a wire, flies, circles around and comes back to its perch. Explain the total distance it traversed during its flight and its eventual displacement.
Advertisements
Solution
The total distance travelled by the bird during its flight = 2×(Distance between the point where the bird was sitting and the point from where it takes a turn)
The eventual displacement of the bird is zero as it returns to its initial point, i.e., where it was sitting.
