In what condition is the acceleration of a falling parachute is zero?

Click For Summary

Discussion Overview

The discussion centers on the conditions under which the acceleration of a falling parachute is zero, exploring concepts related to freefall and terminal velocity. Participants are seeking clarity on the dynamics involved when a parachute is deployed.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • Some participants suggest that the condition for zero acceleration occurs during freefall.
  • Others propose that a parachutist reaches zero acceleration after the parachute opens and they attain terminal velocity.
  • A participant questions the net force acting on the parachute and its acceleration at terminal velocity.
  • There is a request for a clear answer regarding the conditions for zero acceleration.
  • Some participants express uncertainty about the timing of reaching terminal velocity.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the specific conditions for zero acceleration, with multiple competing views remaining regarding the role of terminal velocity.

Contextual Notes

Unresolved aspects include the definitions of freefall and terminal velocity, as well as the dynamics of forces acting on the parachute during descent.

What do you think?
 


I think freefall
 


When a jumper's parachute opens, he or she--hopefully--quickly reaches a terminal velocity. At that point, what is the net force on the parachute and its acceleration?
 


Is it after reaching terminal velocity
 


Still not clear

Is it what?
 


Give me clear answer on it.
