'Sets the velocity Vector of this Point in a ReferenceFrame.
Parameters
frame : ReferenceFrame
The frame in which this point\'s velocity is defined
value : Vector
The vector value of this point\'s velocity in the frame
Examples
>>> from sympy.physics.vector import Point, ReferenceFrame
>>> N = ReferenceFrame(\'N\')
>>> p1 = Point(\'p1\')
>>> p1.set_vel(N, 10 * N.x)
>>> p1.vel(N)
10*N.x'

def set_vel(self, frame, value):

    if (value == 0):
        value = Vector(0)
    value = _check_vector(value)
    _check_frame(frame)
    self._vel_dict.update({frame: value})
