SUMMARY

The discussion focuses on calculating the gravitational field using established physics formulas. The gravitational force is defined by the equation F = GMm/r², while the gravitational potential is expressed as U = -GMm/r. Additionally, the vector form of the gravitational field is presented as -G(m₁/||r||²)−hat{r}. These formulas are essential for understanding gravitational interactions in physics.

PREREQUISITES
  • Understanding of Newton's Law of Universal Gravitation
  • Familiarity with gravitational potential energy concepts
  • Basic knowledge of vector mathematics
  • Proficiency in using physical constants such as G (gravitational constant)
NEXT STEPS
  • Study the derivation of gravitational force equations in classical mechanics
  • Explore gravitational potential energy and its applications in astrophysics
  • Learn about vector calculus and its relevance in physics
  • Investigate the implications of gravitational fields in orbital mechanics
USEFUL FOR

Students of physics, educators teaching gravitational concepts, and professionals in fields related to astrophysics or engineering who require a solid understanding of gravitational calculations.

been a while since i have done physic... for got how to calculate gravitational filed...

<THIS IS NOT A HOMEWORK QUESTION>
 
Physics news on Phys.org
Gravitational force : F = GMm/r^2
Gravitational potential : U = -GMm/r
 
[tex]-G \frac{m_1}{r^2}[/tex]
or in vector form, which I prefer to use:
[tex]-G \frac{m_1}{\left\| \boldsymbol{r} \right\|^2} \boldsymbol{\hat{r}} \,.[/tex]
