Coin rotation paradox

The coin rotation paradox is the counter-intuitive observation that, when one coin is rolled around the rim of another coin of equal size, the moving coin completes two full rotations after going all the way around the stationary coin. (Wikipedia).

What is the difference between rotating clockwise and counter clockwise

👉 Learn how to rotate a figure and different points about a fixed point. Most often that point or rotation will be the original but it is important to understand that it does not always have to be at the origin. When rotating it is also important to understand the direction that you will

Julius Sumner Miller: Lesson 11 - Centrifugal Force and Other Strange Matters

The name "centrifugal" force given to certain events is very often badly used. Consider a car going round a curve. A book lies on the seat beside you. You are the driver. You take a curve to the left - say. As you make the curve you see the book move radially out on the seat - movi

Centrifugal Force Does NOT Exist!!

When it comes to rotation, things get really REALLY weird... so weird, in fact, that you experience things that play tricks on your perception. In this video, I demonstrate this by having fun on a merry-go-round. Video Links in Credits: What The HECK Are Fields? http://youtu.be/nxi8hGeicC
