Kinetic energy of the particle

        The kinetic energy, T, of a particle, P, is given by

        'T = 1/2 m v^2'

        where m is the mass of particle P, and v is the velocity of the
        particle in the supplied ReferenceFrame.

        Parameters
        ==========

        frame : ReferenceFrame
            The Particle's velocity is typically defined with respect to
            an inertial frame but any relevant frame in which the velocity is
            known can be supplied.

        Examples
        ========

        >>> from sympy.physics.mechanics import Particle, Point, ReferenceFrame
        >>> from sympy import symbols
        >>> m, v, r = symbols('m v r')
        >>> N = ReferenceFrame('N')
        >>> O = Point('O')
        >>> P = Particle('P', O, m)
        >>> P.point.set_vel(N, v * N.y)
        >>> P.kinetic_energy(N)
