It looks close to ##\vec g=-Gm\frac{\vec r}{r^3}##, which does make sense,LCSphysicist said:Homework Statement:: Gravitational topic
Relevant Equations:: G = -Gm/r^3
I am doing a book that have only exercises, and an introduction to the posterior theme, so, in the introduction, there is the relevant equations, and there is a equation: G = -Gm/r^3 called strength G, in the gravitational topic, what is this? I never saw it.
The gravitational strength "G" is a physical constant that represents the strength of the gravitational force between two objects. It is also known as the Newtonian constant of gravitation.
The gravitational strength "G" is typically measured in units of newtons per square meter per kilogram squared (N·m²/kg²). This can be determined experimentally by measuring the force of gravity between two objects of known mass and distance.
The gravitational strength "G" is considered a constant because it does not vary based on the masses or distances of the objects involved. It remains the same regardless of the location or environment.
The gravitational strength "G" is responsible for the force of gravity, which attracts objects towards each other. This force affects the motion of objects by causing them to accelerate towards each other.
While the gravitational strength "G" is considered a constant, there are some factors that can affect its value. These include the presence of large masses, such as planets or stars, which can create gravitational fields that can slightly alter the value of "G". Additionally, some theories, such as general relativity, suggest that "G" may vary in extreme conditions, such as near a black hole.
