Question

A hawk leaves her nest, circles it at a fixed distance, then returns to the nest.
While circling her displacement from home is (increasing / decreasing / staying the same)
Over the whole day her displacement from home is (positive / negative / zero)
While returning to the nest her displacement is (increasing / decreasing / staying the same)

Answer 1

- While circling at fixed radius: staying the same (distance from the nest is constant).
- Over the whole day: zero (she ends where she started, so net displacement = 0).
- While returning to the nest: decreasing (the distance from home gets smaller).
