Gravitational Superposition
Three masses; drag a probe and see net F as the vector sum from each.
Key Notes
01
Net gravitational force on a body is the vector sum of forces from each other mass.
02
Always attractive — each force points from the test mass toward each source.
03
For continuous distributions, sum becomes an integral.
Formulas
Superposition
Vector sum.
Important Points
At symmetric points (e.g. center of equilateral triangle of equal masses), forces cancel.
Inside a uniform spherical shell, F = 0 (shell theorem).
