In Hamiltonian mechanics, a function f is only conserved if the sum of its Poisson bracket with the Hamiltonian plus its partial with respect to this variable is zero.
In Hamiltonian mechanics, a function f is only conserved if the sum of its Poisson bracket with the Hamiltonian plus its partial with respect to this variable is zero. When this quantity is cyclic, the energy of a system is conserved. The cycloid is the solution to a pair of problems named for this quantity. This quantity is assumed to be identical between reference frames when using Galilean transforms. (*) Torricelli names an equation that relates the initial and final velocities of an object with constant acceleration with no need for this variable. The directionality of this quantity is oriented with the increase in entropy of the universe and is a namesake arrow. Integrating acceleration with respect to this variable yields velocity, then position. For 10 points, name this quantity typically denoted t and measured in seconds.
