Does relative motion allow for speeds $>c$?
If motion is relative, (so if X was stationary and Y was moving at v m/s, we could think of this as Y being stationary and X moving at -v m/s), could we not create a scenario in which a stationary ...

Having trouble deriving the exact form of the Kinematic Transport Theorem
The Kinematic transport theorem is a very basic theorem relating time derivatives of vectors between a non rotating frame and another one that's rotating with respect to it with a uniform angular ...

Trajectory of particle thrown from the center of rotating frame of reference
So we have a rotating platform with two frames o reference: the one which is static, $O:\{x,y,z\}$, and the one wich is rotating along the platform, $O':\{x',y',z'\}\ (z\equiv z')$. The platform is ...

Will the plane of oscillation of a pendulum change if I rotate the suspension point
I'm having trouble understanding Foucault pendulum and from that I've extracted one of my doubt and here it goes:
A pendulum on a fixed platform is shown
Now if we rotate the platform as shown
Will ...

How do I transform onto a relativistic rotating frame of reference?
In classical mechanics, the usual formula to translate the evolution of a quantity as seen from an inertial frame of reference to a rotational frame is: $$\frac{d \textbf{A} }{dt} \vert_{Inertial} = \...

Uniform circular motion & relative velocity
Consider a car moving along a straight horizontal road at constant speed, $v$.
Also consider one of the tyres/wheel of the car. On it, there are two particles of dust $A$ and $B$ (as shown in the ...
