Friction or not?
Say I have a differential equation in $\mathbb{R}^n$, Newtons Equation :
\begin{align}
\frac{d\gamma(t)}{dt}=&\dot{\gamma}(t),
\nonumber
\\
\frac{d\dot{\gamma}(t)}{dt}=&-\...

What are the necessary and sufficient conditions for a motion to be periodic?
Consider the following idealized motions
(i) The motion of a bob attached to a spring on a horizontal frictionless table,
(ii) the motion of a pendulum with an arbitrary amplitude without air ...

could a force with corolios and centrifugal terms be written as a potential gradient? [duplicate]
I have an exam in classical mechanics next week, so I came across this problem which I did not fully understand nor any of my colleagues (it was a bonus problem in an old exam) I just want some hint ...

Force as gradient of scalar potential energy
My text book reads
If a particle is acted upon by the forces which are conservative; that is, if the forces are derivable from a scalar potential energy function in manner $ F=-\nabla V $.
I was ...
