Hello Forum,
I have been reading a book, the Fabric of the Cosmos, by Brian Greene. It talks about Newton investigating the behavior of water in spinning bucket...
Zero motion (at rest) and uniform motion (constant velocity) are two types of motion that cannot be distinguished: we cannot tell if we are at rest or moving...
But when we are accelerating we surely know we are, we feel that we are. Why? What makes acceleration so special that we are able to realize we are accelerating, while we are unable to tell if we are at rest or moving at constant velocity?
Greens talks about accelerated motion as a curve trajectory n spacetime while uniform velocity as a straight line in spacetime...that seems a very mathematical answer... Absolute space does not exist (As Newton believed)...
Is there a more intuitive explanation of why we feel accelerated motion?
thanks
