Pseudoforces or fictitious forces

AI Thread Summary
Centrifugal and Coriolis forces are classified as pseudoforces because they arise from non-inertial reference frames, where the observer is in an accelerating frame of reference. These forces do not originate from physical interactions but instead result from the inertia of objects within those frames. The distinction is that real forces, like gravity, act directly on objects, while pseudoforces are perceived due to the observer's motion. Understanding this concept is crucial for solving problems in physics involving rotating or accelerating systems. Thus, recognizing the nature of these forces helps clarify their role in dynamics.

Homework Statement




Why centrifugal force, Coriolis force are termed as psuedoforces? Are they not real forces? Please help, revered members.

The Attempt at a Solution


 
Physics news on Phys.org
The short (and I'm sure dreadfully oversimplified) answer is basically just that they're called "fictitious" forces because they're the effects of reference frames that are moving/accelerating relative to each other.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
