Homework Help Overview

The problem involves understanding the forces acting on a bird that is ascending at a steady rate due to an updraft. The main forces in question are gravity and aerodynamic force.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants discuss whether the aerodynamic force must be greater than gravity for the bird to ascend steadily. There is an exploration of the relationship between these forces.

Discussion Status

Several participants express agreement with the idea that aerodynamic force must be greater than gravity for the bird to maintain its ascent. However, the discussion does not reach a definitive conclusion, and the reasoning behind this assertion is still being explored.

Contextual Notes

There may be assumptions regarding the bird's steady rate of ascent and the conditions of the updraft that are not fully articulated in the discussion.

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?
 
Physics news on Phys.org


That sounds right to me.
 


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