  1. Fictitious force aka centrifugal force aka Corioli’s force aka d’alembert’s force aka Euler’s force

    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

    Fictitious forces.
    Coriolis force, Euler Force, d’Alembert force, centrifugal force. Einstein characterized gravity as a fictitious force.

    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.

    Fictitious force

    A fictitious force/a pseudo force,Alembert force (as in D”Alembert) or inertial force is 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 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 consider gravity was a fictitious force as well.
