Reactive centrifugal force is not the same thing as centrifugal force. Reactive centrifugal force is the reaction force. It is the reaction force reacting to a centripetal force.

What is the similarities of centrifugal and centripetal force?
Centripetal Force is more directed towards the center of the axis of rotation of an object following an elliptical or circular path. Centrifugal Force is the force that pulls away from the center because of the objects inertia. Example: If you took a rock, tied it to a string, and swung it around, the force from the center of the axis of rotation is centripetal force. The force that causes the rock to pull away from the center, is centrifugal force. If you have ever been in a fast moving car that sharply turns and you feel as if you are pulled to the side, that too is centrifugal force caused by your inertia. The more mass the more inertia. this answer is very good ============================== But largely erroneous. "Centrifugal" force doesn't exist. It's a make-believe, made-up thing, that's not really there. When the centripetal force suddenly shuts off, the object proceeds in a straight line, in the direction it was going at the instant when the centripetal force stopped, and naturally, the straight line takes it straight away from what used to be the center of its motion. We see the object take off straight away from the former center, and we say "Gee, there must be a force pulling it away from there." But there isn't any. That "force" that you think you feel when the car turns a corner and you get pressed against the door, away from the curve ? That's just the tendency of your body to want to keep moving in a straight line, and its reaction to the centripetal force that the car-seat and the door are exerting on you in order to make your body move in a curved path. There is no "centrifugal" force.
Why is the centrifugal force the ladybug feels in the rotating frame called fictitious force?
This is a term from classical mechanics. A fictitious force is a force that is only present in a so-called non-inertial frame. This means that the observer is experiencing some kind of acceleration. The point is that if the observer is accelerating then he might see some forces that are not really forces at all. If you are in a rotating frame you are accelerating, and you feel a centrifugal force. However anyone looking at you while not rotating themselves will say that there is no such force at all. Imagine you are on a horse in a merry-go-around and the thing malfunctions and starts to rotate very rapidly. You will feel the centrifugal force trying to blow you away from the center. However someone standing next to the merry-go-around sees no such force. What he sees is you holding on to the horse, but it is YOU holding onto the horse that is providing a force, if you would let go you would just fly in a straight line and no force would work on you. It is a little difficult to explain it very well in words, in the relevant links I have posted a link that points to the wikipedia article for the Coriolis force (a fictitious force) and figure 1 there shows a nice picture of the above. In General Relativity however, there is no preference for inertial frames anymore and you are valid in claiming there is a force pushing outwards. This force is then gravity. This is direct consequence of the equivalence principle that states that gravity and acceleration are indistinguishable (in a suitable limit).
Is there such thing as the force?
there is no such thing as the force.

What does apply negtive force to absorb a objects knetc energy mean?
There is really no such thing as "negative force" (force is a vector quantity); in this case, it must be an informal way to refer to a force acting in the direction opposite to the object's movement.
Outward force equal and opposite to a inward force is called?
That's a mythical, nonexistent thing called "centrifugal force".
The type of force that keeps objects moving in a circle or arc?
The type of force that keeps an object such as the Earth moving in a circle is a combination of gravity and centrifugal force. Gravity wants to pull the object inward, but centrifugal force wants to push the object outward. This combination keeps objects going in a circular path. You could also say that, for objects such as a rock attached to a rope that is swung in circles, the forces are the tension of the rope opposing centrifugal force. This is essentially the same thing, except with different forces at work.
What is the difference between a submersible nonclog pump and a horizontal centrifugal pump?
They may be the same thing.
What source keeps the planets in place?
first it is not a source it is a force. There are at least two equal and opposite forces that keep an object in an orbit. Gravity and centrifugal force. Gravity is an attraction which is proportional to the product of the two gravitating bodies divided by the square of the distance between them. Without a force to counteract this attraction, the bodies would move toward each other, the distance decreases, the force between them increase and the two bodies will eventually collide. Centrifugal force on the other hand is a force generated by the radial acceleration of a body moving on a curve. Thus as the planet revolved around a star, centrifugal force is generated which is opposite in direction to the gravitational attraction of the planet and the star. Balance is therefore attained and the planet stays in its orbit. This is the same thing that happens between a star and the core of the galaxy where it is located. The star and its planetary complement revolve around the core of the galaxy and the centrifugal force generated by the revolution counteracts the attraction of the galactic core and the star, hence balance is maintained.
What is the earth's centripetal force?
The term "centrifical" is a word without a definition; some would say a non-existent word. It might have the same definition as "ncauvjnscc" or "oioushc" or any other made up babble you chose to imagine. However, the term has been used enough in common parlance as to associate its meaning with either "centripetal" or "centrifugal". The centripetal force is the force applied to a linearly travelling (straight line) object to make it travel in a curve or to make it rotate about some center point. The force is applied to the object make it move toward that center point. The centrifugal force is referred to as the opposite force to the centripetal force following Newtons Law of equal and opposite reaction. However, this force is a consequence of the inertia of the object (resistance to the circular motion) and acts on the source of the centripetal force, NOT the object experiencing curved motion. The centrifugal force is equal, but opposite, the centripetal force. For instance, a weight on a string attached to an object swung about your head experiences a force applied inward (centripetal force) due to your hand (the center point) applying the force. The string also experiences this force all along its length. Your hand experiences a force applied outward (centrifugal force) due to the weights inertia (resistance to change direction at all points in time as it moves in a circle). The string also experiences this force all along the string. The opposing forces on the string keeps the string in tension. Additionally, your feet share a friction force against the surface you stand on equal to the centripetal force to keep you stationary. So the question remains: which force did you really mean, centripetal or centrifugal?
How old is gravity?
So gravity is basicly centrifugal force (the world spinning) which pulls us and other thing towards the centre of the earth. So gravity has been around for aslong as the world has been spinning.

What is the difference between centrifugal and centripital?
A moving object with no force acting on it continues moving in a straight line. Ittakes a force to bend it away from a straight path. As long as an external forceacts on the object and continues to point toward the same single point, the objectwill move in a circular path, and the force is called a "centripetal force", which meanssomething like "toward the center".Now, hold onto your seat: "Centrifugal" force doesn't exist. It's a make-believe,made-up thing, that's not really there.When the centripetal force suddenly shuts off, the object proceeds in a straightline, in the direction it was going at the instant when the centripetal force stopped.That straight line takes it NOT from what used to be the center of its motion,but on a tangent to that path, straight away from the point it was at when thecentripetal force shut off. Still, we see the object take off straight away fromthe point it was at, and we say "Gee, there must be a force pulling it away fromthere." But there isn't any.That "force" that you think you feel when the car turns a corner and you getpressed against the door, away from the curve ?

There is no "centrifugal" force.Answer2:Centrifugal force is as real as centripetal force, centripetal force is center seeking and centrifugal force is center fleeing. Both forces result form the derivative of the energy. Physicists do not recognize vector energy and this adds to the idea that centrifugl force is fictitous.Here is the real deal, energy is a QuaternionW = -vh/r + cmV = -vh/r + cPwhere -vh/r is the potential energy like -vh/r = -mGM/r and cmV is the vector energy, cP where P is the Momentum. The vector energy, Momentum energy is the so-called "Dark Energy".Force F = XW = [d/dr, Del][-vh/r, cP]F = [vh/r2 - cdel.P, cdP/dr -Del vh/r + cDelxP]F = [vp/r - cp/r cos(PR), -cp/r 1P + vp/r 1R + cp/r sin(PR) 1RxP]The centripetal force is vp/r a center seeking force.The centrifugal force is - cp/r cos(PR), this is the Divergence of the vector energy cP.When the centripetal and centrifugal forces are equal vp/r = cp/r cos(PR), there is no change relative to the center, this is called the Continuity Condition and is the source of the mysterious "redshift", v/c = cos(PR). The redshift is the indicator of the Continuity Condition, stable orbit and vector force,F = cp/r[0, -1P + v/c 1R + sin(PR) 1RxP]cp/r= cp/ct = p/t = mv/t = ma
How do you get artificial gravity on mars 4 years from now?
There is no such thing as artificial gravity Another Answer: Actually there is such a thing as artificial gravity. At least it can be made. Build a huge round object in the shape of a donut. Spin this object and centrifugal force will allow you walk and stand perpendicular to the sides. Another way is the use of magnets located on bottoms of shoes.
What is the different between centrifugal force and centripetal?
Centripetal force is directed toward the center of rotation of an orbiting body or object following a curved path. Centrifugal force is the apparent force, equal and opposite to the centripetal force, drawing a rotating body away from the center of rotation, caused by the inertia of the body. Whenever you see a moving object that's not traveling in a straight line, you know that a force is acting upon it. That's because objects tend to resist changes to their velocities. The greater the mass, the greater the resistance to changes in velocity. That's called inertia. Objects at rest tend to stay at rest, and objects in motion tend to stay in motion, unless acted upon by some external force. (See Newton's First Law.) Since velocity is a vector -- remember vectors have magnitude AND direction -- any change in an object's direction constitutes a changes in its velocity. When an object is flying around in a circle, its velocity is constantly changing because its direction is constantly changing! That means a force is working on it. That force is the centripetal force, and since force is equal to mass times acceleration, there must be an acceleration involved. You guessed it -- centripetal acceleration. There is a girl on a bike with a jump rope. Her spinning the bike pedals in centripetal force, though her spinning the jump rope around her is centrifugal force. The pedals are designed to keep the motion contained in a small area, keepiing the girl's feet right where they are, but the jump rope lashes out, with the chance of the girl losing her grip on it, due to its force. Centripetal Force is more directed towards the center of the axis of rotation of an object following an elliptical or circular path. Centrifugal Force is the force that pulls away from the center because of the objects inertia. Example: If you took a rock, tied it to a string, and swung it around, the force from the center of the axis of rotation is centripetal force. The force that causes the rock to pull away from the center, is centrifugal force. If you have ever been in a fast moving car that sharply turns and you feel as if you are pulled to the side, that too is centrifugal force caused by your inertia. The more mass the more inertia.

What is the round thing in the window of fishing boats pilot house?
It's called a SPEICH. It keeps a glass disk free from rain, snow or sea-water by fast rotation, using centrifugal force to keep water, snow and ice from sitting or building up on the window to maintain visibility.
