What Are the Effects of the Euler Force?

Click For Summary
The Euler force is a fictitious force experienced by an observer in a rotating reference frame when there is a change in the rotation speed. It acts perpendicular to the centrifugal force and is felt as a counter-clockwise push when a disk starts to rotate clockwise. This force arises due to the inertia of the observer, who may not be aware of the rotation. Understanding the Euler force is crucial for visualizing dynamics in rotating systems, especially alongside centrifugal and Coriolis forces. The discussion highlights the importance of grasping these concepts for better comprehension of rotational motion effects.

Can anyone describe what the effects of the Euler force are? If you're not familar with it, it is a fictitious force that arises from a rotating object undergoing a change in rotation speed. Can someone tell me what the effects of this fictitious force are?

It should be something like this: suppose you're standing on a disk initially at rest. Then it starts to rotate, say clock-wise. At that time, the (inertia-)force you feel that is pushing you counter-clockwise is Euler force.
 
I'm trying to visualize it this way - if I was in a rotating coordinate system, (but unaware of it!), centrifugal force would be in one direction, coriolis would be a repulsive force (from me), and euler force would be perpendicular to centrifugal. I could be wrong, but I think it's a good question and I'm at work right now.
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
