Centrifugal - is the direction of motion at a given time without any force keeping "it" in orbit
Centripetal - is the direction of motion at a given time keeping "it" in orbit
Velocity - is the direction of motion at a given time directing "its'" motion in orbit
Centripetal acceleration
is the change in the velocity due to the centripetal force





Context:
Centrifugal force isn't real.

Well....one is the acceleration, the other is a force :francis:


I'll try and break it down :yeshrug:

Lets break it down to pieces then build it back up.

Position - is any given point/location in space ( I.E. the chair on yo granma porch)
Vector - direction(starting position & ending position) and magnitude(distance between two position)

Velocity - is a vector change in position over some given time(I.E. from the chair to the front door took 5second)
Acceleration - change in velocity over some given time

Force - anything that changes your velocity
Centrifugal - moving or directed outward from the center
Centripetal - moving or directed toward the center

centripetal acceleration - now a small catch would be...

"why is it called centripetal acceleration instead of centripetal force?"

Centripetal acceleration is the change in the velocity vector due to the centripetal force. Otherwise it would theoretically keep going straight in the direction of V(the velocity vector)

Critical note:
The change in the velocity vector isn't due to a change in its' magnitude. It's due to a change in its' direction.

Lets break it down to peices then build it back up.

centrifugal force is an apparent "force" just like the "force" you feel pushing you back into your seat when you accelerate, it's actually the seat pushing you forward.

Yeah, for me to talk about that fictive/inertial force i'd have to get into component vectors to show where the inertia comes from. The bad part about talking about centri forces is that it's hard to give a clear talk about them in snapshot form. There are forces at play from previous time stamps in the loop that aren't spoken of in the snapshot.

most teachers teach physics wrong

the best way to learn physics is to see how the equations were derived

it makes so much more sense, even if it gets a little complicated.

I would say...
1st Delineate whats being discussed by simply showing the phenomena(no math)
2nd Show "how the equations were derived" (introduce and clearly explain the mathematical tools which deal with that type of motion)
3rd Show "how the equations were derived" (use those tools to derive the simplified formula describing the phenomena)

Did you major in physics?

Software engineering at Auburn University. All engineering courses require the common core engineering curriculum. So I've taken engineering physics 1 & 2 along with principles of engineering(so that you are ready to take the PE exam)

NCEES(National Council of Examiners for Engineering and Surveying) PE exam

PE exam
The Principles and Practice of Engineering (PE) exam will test your ability to practice in a particular engineering discipline competently. It is designed for engineers who have gained at minimum four years’ post-college work experience in their chosen engineering discipline. Each PE exam lasts 8 hours and is split into a morning and an afternoon session.
