Not if one is claiming that anything is accelerated by it, it doesn't.

You know that velocity can be changed by centrifugal force.

Velocity and direction are just vectors.  These can be easily changed.

No, it can't.

Direction is not a vector. Direction is a part of what makes up a
vector: direction and quantity.

Not now, I can't.

I found my limit with all of the diff-e in a graduate level stellar
interiors class.    I wasn't going to use it then anyway (I was in
AFROTC), and never got back to physics when I left the USAF.

As described,  wouldn't the centrifugal force be the release of
 the flex in the shaft of the club?

Yes it can.

A vector is a quantity having both magnitude and direction.  If the
velocity is a unit then the direction makes the vector.  I'm not
saying that you are wrong.

Don't drink and drive.  Unless you have a good cup holder.

I know what a vector is. You by your earlier statement showed you did
not.

I can do it in my sleep.

Then maybe you can appreciate my mathematics.  When I wrote that
program the DOD didn't have the best computers.  I wrote my program
using punchcards.

Hyperbolic acceleration around a gravitonal field is well known to
scientists.

Which has absolutely nothing to do with centrifugal forces...

And it's not "hyperbolic acceleration" at all. It's acceleration due to
gravity which happens to create movement that is in the shape of a
hyperbola.

OK, we're going to go through this again.  I WAS WRONG. I made a
slight error.  velocity is a scalar and direction is a scalar.  You
need to add them together to get a vector.

Are you happy now?  I always assume that everything is a vector.  If
direction is 30 degrees I assume that there is a velocity from 0 to c.
And if there is a velocity there has to be a direction.  That's just
the way things happen.  Unless velocity is zero and direction is zero.

Don't drink and drive.  Unless you have a good cup holder.
