SUMMARY

This discussion focuses on modeling the motion of a balloon filled with air, emphasizing the physics behind its behavior when thrown upwards. Key equations include Newton's second law (F=ma) and the relationship between distance and velocity (distance = vt). The balloon's descent is influenced not only by its low mass but significantly by its large cross-sectional area, which increases air resistance. The discussion also touches on the orientation of the balloon during flight, likening it to the behavior of a badminton shuttlecock.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Basic knowledge of kinematics equations
  • Familiarity with concepts of air resistance and drag
  • Awareness of the principles of buoyancy and density
NEXT STEPS
  • Study the effects of air resistance on falling objects
  • Learn about the equations of motion in fluid dynamics
  • Explore the principles of drag force and its calculation
  • Investigate the behavior of projectiles with varying shapes and masses
USEFUL FOR

Physics students, educators, and hobbyists interested in understanding the dynamics of objects in motion, particularly those exploring the effects of air resistance and fluid dynamics on lightweight objects like balloons.

I want to model the motion of balloon filled by a human not helium or any other gas.

what would be the equations? I know the air would've some mass so if I throw the balloon up that would f=ma ? distance = vt?

when a balloon comes down its downward motion is much slower say compare to a tiny metal piece, I assume that's because of low mass of balloon?

any other details would be appreciated.
 
Physics news on Phys.org
It is not really because of the low mass- all objects, of any mass, fall with the same acceleration in absence of air resistance. It is the large cross sectional area, pushing aside air, in combination with its low mass, that affects its acceleration.
 
so then what equations do apply? how do i determine what is slowing the vertical velocity of balloon?

also I've noticed that everytime I throw the balloon up it tries to make it down such that its air noozle is pointing down (most of the time) more like a badminton shuttle, is this a given or only happens in certain scenarios?
