Intuition behind energy not being conserved in Rheonomous mechanical system [closed]
firstly, this is what Rheonomous System means. So, in such a system, the kinetic energy is not exactly just a quadratic function of generalized velocities because one of the generalized coordinates ...

Calculate period time from potential energy [duplicate]
The question asks:
The potential energy of a particle in one dimensional space is:
$$
U = \frac{1}{2}Ax^2 + \frac{1}{4}Bx^4
$$
I need to calculate the period time, from the period calculate the ...

Why does the law of conservation of energy not hold true when the work-function $U$ depends explicitly on $t$?
[...] the infinitesimal work $\overline{\mathrm dw}$ comes out as a linear differential form of the variables $q_i$: $$\overline{\mathrm dw}= F_1~\mathrm dq_1 +F_2~\mathrm dq_2+ \ldots + F_n~\mathrm ...
