SUMMARY

The discussion focuses on calculating the buoyant force exerted by helium against gravity. Specifically, it addresses how one kilogram of helium generates a pushing force of approximately 5 Newtons in opposition to the gravitational vector. The acceleration of helium is noted to be 1 meter per second squared. The conversation emphasizes the importance of understanding buoyancy in the context of lighter-than-air gases.

PREREQUISITES
  • Basic understanding of physics principles, particularly buoyancy.
  • Familiarity with Newton's laws of motion.
  • Knowledge of the concept of gravitational force.
  • Understanding of vector forces in physics.
NEXT STEPS
  • Research the principles of buoyancy and Archimedes' principle.
  • Learn how to calculate buoyant force using the formula: Buoyant Force = Weight of Displaced Fluid.
  • Explore the properties of lighter-than-air gases, focusing on helium.
  • Study the relationship between mass, weight, and gravitational acceleration.
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in understanding the mechanics of buoyancy and the behavior of gases like helium in gravitational fields.

Hey,
I'm not very good in physics but i have something which seems like a basic question only i could not find the answer.
I'de like to know how to calculate the pushing force of helium towards one kilogram of mass (a vector to the opposite direction of gravity.). For example - one kilogram of helium will apply 5 Newtons against gravity vector. Or - for example -t he acceleration will be 1 meter/sec^2..
To conclude - anything hich will give me indication of how much force wwill it apply.
Thanks,
Gabriel

Hey Gabriel! :smile:

You're asking for the buoyant force … see eg http://en.wikipedia.org/wiki/Lighter_than_air" :wink:
