What does centrifugal force means?

Question

What does centrifugal force means?

Answer 1

In English we say 'what does it mean' (no 's') OK?

Skipncat's answer is nearly correct. There are two forces (always) centripetal and centrifugal in this case, equal and  opposite in direction.

Both are real; there's no such thing as a 'fictitious' force, to my knowledge (or Newton's.)

  

Answer 2

Centrifugal ("center fleeing") force is a fictitious force.  The actual force acting on the bucket referred to above is centripetal ("center seeking") force.  The centripetal force changes the direction of the bucket of water.  On your arm it feels like the bucket is pulling away from you.  However, your arm supplies the centripetal force that changes the tendency of the bucket to go in a straight line.  

Answer 3

It is like when you have a pail of water and you spin it around in a vertical circle the water won't fall out because the force from the center is pushing outwards. It basically means a center of force which is going outwards at a 360 degree circle.
