What? Not really…
What connects?
Cracked by everyone!
Answer:
Fictitious forces!
- Coriolis
- Einstein
- Euler
- d’Alembert
- An XKCD strip referencing the fictitious nature of centrifugal force.

Answer:
Fictitious forces!
Fictitious force aka centrifugal force aka Corioli’s force aka d’alembert’s force aka Euler’s force
Fictitious forces
Some of the fictitious forces in nature..
Coriolis, Gravity, Euler, Centrifugal et al.
Nice one :)
Pseudo forces
Fictitious forces
the concept of ‘fictitious forces’ – coriolis, gravity/einstein, euler, d’alembert, and the last one i’m guessing is a reference to centrifugal force
Fictitious force or d’Alembert force
They are forces that one feels in an non inertial frame…..(a frame which is accelerating)
1>Coriolis force(the frame is rotating)
2>Einstein force
3>Euler force(when there is angular acceleration)
4>d’Alembert force or pseudo force(forces in non inertial frame of reference)
5>xkcd centrifugal force
Coriolis, Einstein (gravity), Euler, d’Alembert, XKCD 123 (centrifugal)
Fictitious forces.
Fictitious forces.
Fictitious forces.
Coriolis force, Euler Force, d’Alembert force, centrifugal force. Einstein characterized gravity as a fictitious force.
Coriolos, Gravity, Euler, D\’Alembert, centrifugal forces
Connect psudo/fictitious forces

pseudo forces
pseudo forces
fictitious force, or d’Alembert force
fictitious forces – d’Alembert, Einstein, Euler, Coriolis and centrifugal forces.
2 : most likely Einstein.
5 : xkcd about centripetal/centrifugal force.
3 : Euler

All these are varieties of Fictitious forces, under various types of conditions.
Coriolis, Einstein (Gravity), Euler, D’alembert, and centrifugal.

Fictitious force
A fictitious force, also called a pseudo force,Alembert force or inertial force,an apparent force that acts on all masses in a non-inertial frame of reference, such as a rotating reference frame.Four fictitious forces are defined in accelerated frames: one caused by any relative acceleration of the origin in a straight line (rectilinear acceleration),two caused by any rotation (centrifugal force and Coriolis force) and a fourth, called the Euler force, caused by a variable rate of rotation, should that occur.All fictitious forces are proportional to the mass of the object upon which they act, which is also true for gravity.This led Albert Einstein to wonder whether gravity was a fictitious force as well.
