Question

A maple leaf falls from a tree branch.



From whose reference point is the leaf moving away from the observer?
A.
a bird standing beneath the tree
B.
a bird perched on the top of the tree
C.
a squirrel sitting beneath the tree
D.
an insect clinging to the leaf

Answer 1

B. a bird perched on the top of the tree.

Explanation: relative to the bird on top, the leaf falls downward away from that observer. The insect clinging to the leaf moves with it (no relative motion), and observers beneath the tree see the leaf moving toward them, not away.
