( r ) (distance from rotation axis) Kinetic energy: ( T = \frac12 m (\dotr^2 + r^2\omega^2) ) – note the centrifugal term emerges naturally. Potential energy: ( U = 0 ) (horizontal plane) Lagrangian: ( L = \frac12 m (\dotr^2 + r^2\omega^2) ) Let ( x ) = horizontal position of
Let ( X ) = horizontal position of the wedge (positive to the right). Let ( x ) = horizontal position of the block relative to the wedge, measured down the slope. The block’s absolute horizontal coordinate: [ X_\textblock = X + x \cos\alpha ] Vertical coordinate of the block (taking table as ( y=0 )): [ Y_\textblock = -x \sin\alpha ] (the minus sign because block moves downward as ( x ) increases). lagrangian mechanics problems and solutions pdf
Use (\dot\phi = \ell/(mr^2)) in energy: (E = \frac12 m \dotr^2 + \frac\ell^22mr^2 - \frackr). Effective potential: (U_\texteff(r) = \frac\ell^22mr^2 - \frackr).
