Gravity (gravitational force)
.The force of gravity is the force which acts on all subjects. The direction toward the center of the world. Is the force that keeps an object attached to the earth. Otherwise, the object or even the atmosphere is blown off in Arriaga.Two objects, Newton's law of gravitation published with MLB movement clause in his third year.Since 1687, we may publish this rule as follows:
"All this particulate matter universe attracts every other particle with a force which is directly proportional to the product of. Mass of the particles and inversely proportional to the square of the distance between the two particles "
.Object of mass m to the gravity acting on the object size as
f = mg
on g = acceleration due to gravity of the earth
= 9.81 m / ss
if m is in kg
f the unit of New. Newton
I f this is what we often call "weight" (weight) because g is the change in the position of the force f is the change with little
human astronauts on the moon (g = 1.6 m. / s.s), it weighs less than the size of the Earth, about 1/6 as much space
g force f is 0, so the value is zero. This condition is called "weightless"
