    A pendulum swings back and forth and has a kinetic energy of 400 J at a

    particular point in its path.? which of : When the kinetic energy is zero, the potential energy will be 400 J greater. The minimum kinetic energy is zero. The potential energy increases when the kinetic energy decreases. Both the kinetic and potential energy are decreasing.
