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 centripetal force also called an inward force?
Yes. Centripetal is center seeking force. Centrifugal is center fleeing force.
How has the world cup changed since 1930?
In 1930 it was called the Jules Rimmet trophy , till 1970. That year Brazil won its third world cup, and according to the old rule Brazil were allowed to keep it. But in 1974 world cip a new gold cup was made and this is a rotating cup.

A baby ladybug is called a larva.
What would happen is the world started to rotating as fast as it does know?
If you intended to ask why the world started rotating at its current speed in its current orbit, the centripetal and centrifugal forces of all heavenly bodies are considered to have their origin in what is universally called the Big Bang theory.
What is the name of ladybug shell?
The name of a ladybug is called the 'elytra'
What are two forces that keep the planets revolving around the sun?
The force of gravity pulls the planet towards the Sun and this is balanced by the planet's "centrifugal force" away from the Sun. (Centrifugal force is called a "fictitious force" in physics. It's a mathematical way of representing the planet's tendency to move in a straight line path. Some people prefer to talk about the planet's "inertia" rather than centrifugal force.)
A particle in the surface of a mass of liquid moving with linear acceleration has its force acting each weight and the fictitious inertia force which is sometimes called as?
You may be referring to the 'fictitious' Coriolis effect or more correctly, Coriolis force. The Coriolis force is a fictitious force that arises from viewing things from the perspective of a rotating reference frame. When viewed from the perspective of an inertial frame, the "force" doesn't appear. We (on Earth) tend to use rotating reference frames because this view is convenient for describing behaviors that nearly co-rotate with Earth. Jeannie Heroux

How do you spell ladybird in French?
Ladybird, or as we call it in the US, ladybug, in French is coccinelle.
What is the scientific name ladybird?
The ladybird or ladybug actually is a family of species, called Coccinellidae. If you want the scientific name a specific ladybug, count the spots, because a species normally has a specific amount of spots.
What is centrifugal forc?
Think of it this way. Let's say you have a yo-yo and let it unwind. Then you start swinging it around your head in a circle parallel to the ground. The force that keeps the yo-yo in its circular path is the centripetal force (centripetal = away from the center). Without it, the yo-yo would not continue in its circular path but would fly off in a straight line, which it is inclined to do. The tension in the string is the centripetalforce. The centrifugal force is a fictive force: it is, in fact, the "feeling of repulsion" caused by the yo-yo's inertia. Remember Newton's First Law : an object in motion tends to keep a linear path at a constant speed.The fictitious (or apparent) force that appears to act away from the center of the point of application of the centripetal force is the centrifugal force; it's what you feel when you drive around a tight curve. Note that "nothing" is pushing you outward ... rather the car seat is pulling you inward.
