So you are suggesting that a body in motion tends to stay in motion. i.e. there are no forces acting on the train (or me on the pond), so I will keep right on moving with the earth. I can see that.
Consider for a second coriolis acceleration. If you fire a projectile a long distance, the Earth...
Well, that's my confusion. If the Earth is a truly rotating reference frame, it moves with respect to a reference frame at rest. So, the Earth has imparted an initial speed of 1000 mph to the train with respect to the non-moving reference frame. But then the Earth no longer influences the train...
Homework Statement
Will a maglev train beginning at rest slowly drift or accelerate due to the rotation of the earth?
Homework EquationsThe Attempt at a Solution
The Earth is a rotating reference frame, with points on the equator moving at approximately 1000 miles per hour. If the maglev is...
I can only think of fluids as such, water and atmosphere. Those have different behaviors though.
One man-made object that approaches frictionless would be a mag-lev train.
Similar question, would a mag-lev be (slowly) induced into movement by coriolis or other rotational Earth force if it was...
Homework Statement
Will a frictionless body placed on the Earth move, and if so, describe it's path and acceleration.
Homework Equations
I was given no equations, but I believe that coriolis and centripetal forces would act on the body.The Attempt at a Solution
I assume that we have to assume...
