What is the force pulling outward when something moves in a circle?

Answer 1

Unless that object has something connected to it that generates such a force, there

is no force on something merely because it's moving in a circle. It feels like it, but

that's only because the object is always trying to proceed in a straight line from

where it is, and you have to resist that tendency to convince it to bend in a circle.

The feeling is so convincing that a name has been given to the outward force that

doesn't actually exist. It's called "centrifugal force". But it's a myth, and there's no

actual force pulling the object outward.

Answer2:

There is a force pulling outward when an object is moving in a circle, the force is the divergence of the Momentum Energy, the vector energy, the "Dark Energy", cP.

A moving object has momentum P=mV and vector energy cmV. The Divergence of this vector energy is Del.cP= -cp/r cos(P), and this is the centrifugal force! Centrifugal force is a real, scalar force. The negative sign indicates outward force.

The centrifugal force is the vector derivative of the "Dark Energy' cP. Physicists define energy as a scalar and thus cannot "see" the vector energy cmV, right before their eyes. Energy is a Quaternion Quantity W = V + K where V is the potential (e.g. -mGM/r or -vh/r) and K is the "Kinetic" vector energy cP.

The Quaternion derivative is X= d/dr + Del = [d/dr, Del]= [d/cdt, Del].

The derivative of cP is

F= Xcp= [d/dr,Del][,cP] = [-cDel.P, cdP/dr + cDelxP]

F= [-cp/r cos(P), cdP/cdt + cp/r sin(P) 1RxP]

F= [-cp/r cos(P), dP/dt + cp/r sin(P) 1RxP]

the vector energy cP gives the centrifugal force (Divergence) cDel.P, the Tangent force cdP/cdt = dP/dt and the circular force (Curl) cDelxP.

Physicists need to recognize that the Universe consists of Quaternions, the sum of a scalar and a vector quantity. This is a four dimensional space and needs a four dimensional calculus, X = d/dr + Del = [d/dr,Del].

Answer 2

The force pulling outward when something moves in a circle is called centrifugal force. This force acts outward from the center of rotation and is a result of inertia trying to keep an object moving in a straight line.
