Limitations on Newton`s 2nd Law
... The phenomenon of "weightlessness" occurs when there is no force of support on your body. When your body is effectively in "free fall", accelerating downward at the acceleration of gravity, then you are not being supported. The sensation of apparent weight comes from the support that you feel from t ...

... Answer: NO! It might not be true. The expression sN is the maximum possible force of static friction. The force of static friction can be any values less than this maximum: Fstatfric sN. If the barrel is turning so slowly that the rider is just about to slip down the wall, then Fstatfric = sN. ...
