Well, continuing with the daily challenge of the community, I want to give special thanks to @sirknight and the community of @steemchurch for the beautiful creation of this #celestialchallenge.

The Centrifugal Force

Centrifugal force is a fictitious force that appears when describing the movement of a body in a rotating reference system, or equivalently the apparent force perceived by a non-inertial observer in a rotating reference system.

The qualifier "centrifugal" means "flee from the center". In effect, a non-inertial observer on a rotating platform feels that there is a "force" acting on him, which prevents him from remaining at rest on the platform unless he applies another force directed towards the axis of rotation. Thus, apparently, the centrifugal force tends to move objects away from the axis of rotation.

The centrifugal force of the earth could make us float; if the planet rotated so fast that the orbital velocity was achieved on its surface (the one at which the body would be in orbit around the Earth, like an artificial satellite) anyone would stop feeling the weight and it would remain floating in the air. but for that I should get the Earth to give almost half a revolution per minute.

Two examples of this force in everyday life, is how the washing machines work in the drying function and the process of getting the plasma from the blood, the plasma is less heavy than the red blood cells and by means of the centrifugation it can be extracted.

Newton deduced that a force must act on the planets to keep them revolving around the sun instead of moving in a straight line, as would a body on which it exerts no force. After reflecting and analyzing the facts, I conclude that the force that attracts objects to the surface of the earth and that which keeps the stars revolving around other stars is the same.

He deduced that for this force it is fundamental to consider the masses and the distances that separate the objects. With the data available Newton tried to calculate the acceleration with which the bodies fell and concluded that the force of attraction decreased as the body moved away from the earth.

It is surprising what a well-founded theory can do. Newton's laws can not only explain the movement of objects but they are applied in all cases where there are movements and forces, regardless of the causes that produce it.

Newton's Laws are considered one of the contributions
most important of physics to humanity, they remain in force
making possible the scientific and technological advance.
Without a doubt Newton modified forever
the way we see the world.
