What is the significance of gravitational units in understanding momentum?

Click For Summary
SUMMARY

The discussion centers on the concept of gravitational units, specifically how they relate to force and momentum. Gravitational units, often referred to as "G's," represent the force experienced due to gravity, calculated as F=mg, where g is the acceleration due to gravity (9.8 m/s²). The conversation highlights that when discussing momentum in gravitational units, one must consider the force experienced in terms of G's, leading to the formula F=m(#G's)g. The distinction is made that the "G" in this context is not the gravitational constant.

PREREQUISITES
  • Understanding of Newton's Second Law (F=ma)
  • Basic knowledge of gravitational acceleration (9.8 m/s²)
  • Familiarity with the concept of momentum (p=mv)
  • Awareness of the difference between gravitational units and the gravitational constant
NEXT STEPS
  • Research the application of gravitational units in physics, particularly in dynamics.
  • Explore the relationship between force, mass, and acceleration in different gravitational fields.
  • Study the concept of momentum in various gravitational contexts, including planetary bodies.
  • Investigate the historical context and relevance of the gravitational metric system.
USEFUL FOR

Students of physics, educators teaching mechanics, and anyone interested in the application of gravitational concepts in real-world scenarios.

What are gravitational units??

My teacher recently taught us about gravitational units... she said that its the absolute unit multiplied by acceleration due to gravity... I did not understand the significance of this...Please help me
 
Physics news on Phys.org


I have never heard of "gravitational units", but based on your second phrase, "… she said that its the absolute unit multiplied by acceleration due to gravity…", I would guess that she is referring to what is commonly called "G's"; as in , " The astronauts experienced 4 G's during their blastoff."
Assuming this is what she meant, then this is an expression of force in terms of the force due to gravity at sea level on earth.
If you stand on Earth at sea level, the force on you is F=mg where g is the acceleration due to gravity at sea level on earth(i.e. 9.8 m/s^2).
If you next were to stand on another planets surface where you felt two times the force of gravity you felt on Earth then the equation could look like
F=2mg=m2g
so that you weigh twice what you did on earth, hence you feel 2"G's".
So the general rule is when you are given the number of "G's" you multiply that times the acceleration g(9.8m/s^2) to find the force.
F=m(#G's)g.
Hope this helps.
(note:The G used here is NOT the gravitational constant)
 


tnx that was quite helpful... but em not sure if she meant the same thing... ..I can't find nything in my textbook .today...she asked us. "what is the gravitational unit of momentum?"...there's an article on ...Gravitational metric system in wikipedia... Looks like its an outdated one...anyway thanks!
