Laws of Gravitation Flashcards
What is gravity
force on a falling object same type as the force on a planet revolving around the sun
One of the 4 fundamental forces!
The bigger the mass..
the more force it has
The bigger the distance…
the less attracted they are
Law of gravitation formula
Fg= Gm1m2
_____
r^2
For spherical objects, assume all mass is
concentrated in the center
Relationship between objects and their forces?
The forces are opposite and equal (Even if the masses are different)
Gravitational forces are always
attractive
Forces are always equal, opposite, and attracted but when distance increases…
It has a less attractive forcr
Weight is actually
The force of gravitational attraction between the earth and the mass of the body in the question
Formula for gravitational field strength
g= G* m
__
r^2
What kind of quantity is Field strength
vector
On a spherical object, what is the relationship between Fg and m?
Fg and m have a direct relationship
On a spherical object, what is the relationship between Fg and r
Fg and r have a indirect squared relationship
