Question

The hummingbird shown here must beat its wings repeatedly to hover over flowers and drink nectar. What force does the beating of the hummingbird’s wings overcome?

Answer 1

First of all it would be better if you could show the picture.but assuming that it is a bird which is flying here is the answer.

1. it must overcome the gravitational force.

2. the flapping of wings causes friction so it also has to overcome the friction.
