... In the absence of external forces, an object at rest remains at rest and an object in motion continues in motion with a constant velocity. What does this statement tell us? 1. When no force is exerted on an object, the acceleration of the object is 0. 2. Any isolated object, the object that do not i ...

... frame) then Newton's Laws don't hold. However, we can pretend that Newton's Laws hold in an accelerating frame if we pretend that "pseudo-forces" exist. That is, we can get the right answer if we makes two mistakes. In my opinion, this is a Devil's bargain. Computational convenience has come at the ...
