What is the difference between centrifugal and centripital?

Answer 1

A moving object with no force acting on it continues moving in a straight line. It
takes a force to bend it away from a straight path. As long as an external force
acts on the object and continues to point toward the same single point, the object
will move in a circular path, and the force is called a "centripetal force", which means
something 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 straight
line, 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 the
centripetal force shut off. Still, we see the object take off straight away from
the point it was at, 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.

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 Quaternion

W = -vh/r + cmV = -vh/r + cP

where -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

Answer 2

There is no such thing as centrifugal.

Centripetal force is the force that pulls towards the centre of a circle. If you spin a ball around your head the ball will try and move in a straight line but the string pulls it in towards you.

Centrifugal force can not exist because it defies newtons first law.
