Force: Gravity

Question	Answer
Newton's law of universal gravitation	The force of attraction between two masses is proportional to the product of their masses, and inversely proportional to the square of the distance between them
Formula for Newton's law of universal gravitation	F = G(m1 x m2)/r²
Acceleration due to gravity	The acceleration experienced by a body in free fall within the gravitational field of a massive body
Air resistance	Provides an opposing force that reduces the acceleration due to gravity
Value of acceleration due to gravity on Earth	9.8 m/s²
G = ?	Universal constant of gravitation
Formula for gravity on a planet	g = GM/R²
Size of gravitational force between two objects	Tiny, unless at least one of the masses involved is huge (i.e. planet, or star)
