Aerodynamic force of bird problem

[harp AP 2010]

Homework Statement

A bird is caught in an updraft and ascends at a steady rate. Which has greater magnitude: gravity or aerodynamic force?

Homework Equations

The Attempt at a Solution

Is it the aerodynamic force because the bird is moving up, against gravity?

That sounds right to me.

 

[donutz610]

Yes because it must be greater to counteract the force gravity exerts on the bird. It is the aerodynamic force.
