Coriolis Coriolis force Force

Click For Summary

The Coriolis force is a result of the Earth's rotation, causing moving objects to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. It is not a real force but an apparent effect observed in a rotating reference frame. The Coriolis effect influences weather patterns, ocean currents, and ballistic trajectories. To calculate the Coriolis force, one can use the formula F_c = 2mvωsin(φ), where m is mass, v is velocity, ω is the angular velocity of the Earth, and φ is the latitude. Understanding the Coriolis force is essential for fields like meteorology and oceanography.

Homework Statement: Find the perpendicular component of N in an inertial frame and in a non-inertial frame

Relevant Equations: newton equation for non inertial frames

I know that the perpendicular force is the Coriolis force, but I don't know how to get it

Do you know what causes the Coriolis effect ? Why it exists. What is the other force ?

Thread 'Chain falling out of a horizontal tube onto a table'

My attempt: Initial total M.E = PE of hanging part + PE of part of chain in the tube. I've considered the table as to be at zero of PE. PE of hanging part = ##\frac{1}{2} \frac{m}{l}gh^{2}##. PE of part in the tube = ##\frac{m}{l}(l - h)gh##. Final ME = ##\frac{1}{2}\frac{m}{l}gh^{2}## + ##\frac{1}{2}\frac{m}{l}hv^{2}##. Since Initial ME = Final ME. Therefore, ##\frac{1}{2}\frac{m}{l}hv^{2}## = ##\frac{m}{l}(l-h)gh##. Solving this gives: ## v = \sqrt{2g(l-h)}##. But the answer in the book...
