Final answer:
The feather behaved most like the tinsel orb when it fell to the ground due to its large surface area and lightweight, causing them to experience a high amount of air resistance and slower descent compared to other objects.
Step-by-step explanation:
The object that behaved most like the tinsel orb when it fell to the ground is the feather. Both the tinsel orb and the feather have a large surface area and are lightweight, causing them to experience a high amount of air resistance. This air resistance slows down their descent, resulting in a slower fall compared to the other objects.
On the other hand, objects such as the book, penny, crumpled paper, flat paper, and tennis ball are denser and more compact, leading to less air resistance. Consequently, these objects fall faster than the tinsel orb and feather.
