12. A method for activation control of a downhole tool, comprising:
positioning a movably positionable sealing ball proximate to a check valve seat; and
positioning the sealing ball and check valve seat between a source of fluid pressure
and a movable component in a first position, the sealing ball and check valve seat forming a check valve that prevents the movable component from extending outwardly, to a second position, from the downhole tool during rotation when the sealing ball is seated in the check valve seat to affect revolution-per-minute (RPM), abate lateral shock or affect inclination of the downhole tool, and permits the movable component to activate by extending outwardly from the downhole tool during rotation when the sealing ball is unseated in the check valve seat; wherein the alteration in RPM, a reduction of the lateral shock, or a change in inclination causes the sealing ball to seat in the check valve seat by gravity effect to stop the fluid pressure from flowing to the movable component thereby permitting the movable component to return to the first position.
