The Mystery of Pseudo/Inertial Forces: Explained

[NEILS BOHR]

Why are pseudo forces also sometimes called INERTIAL FORCES , even though their need arises because of non inertial frames??

My guess would be because it was the only way to connect them to Newtonian physics such as how centripetal acceleration gets plug in.

They are called "inertial", because they are a consequence of the tendency to move inertially. In non-inertial frames this inertial movement implies coordinate accelerations. Only for massive objects we can then assign a pseudo-force proportional to mass to them.

hmmm
ok thanks for ur answers!

Pseudo or inertial forces are often referred to as "fictitious" forces because they only exist in non-inertial frames of reference. In other words, they are not actual forces acting on an object, but rather the result of the object's motion being observed from a non-inertial frame.

The term "inertial forces" can be misleading because they are not true forces in the traditional sense. However, they are called inertial forces because they arise due to the inertia of the object in the non-inertial frame. Inertia is the property of an object to resist changes in its state of motion, and in a non-inertial frame, this resistance to change can manifest as a pseudo or inertial force.

It is important to note that these forces do not actually exist in the physical world, but rather they are a mathematical construct used to simplify the equations of motion in non-inertial frames. They are necessary in order to accurately describe the motion of objects in these frames, but they do not have any physical manifestation.

In summary, pseudo or inertial forces are called "inertial" because they arise due to the inertia of objects in non-inertial frames, but they are not actual forces. They are a mathematical tool used to describe the motion of objects in these frames and are not present in the physical world.
