A man is holding a closed cage on the palm of his hand with a bird in it.
When the bird flies with an upward acceleration inside the cage, it feels heavier.
But the force due to the bird in the cage is actually an internal force on the cage, and internal forces don't cause acceleration of the body, then how does the cage feel heavier?
