It is important to note that an experiment where gravity sets the arm of the pendulum in motion has never been done. In Cavendish experiments the arm is set in motion by disturbing the pendulum. If gravity has the power to pull the arm, and physicists say that it does, why don’t they let gravity set the arm in motion? One simple answer is that there is no such force.
Physicists themselves set the pendulum arm in motion and at the extreme point of the oscillations when the arm is stationary physicists invoke a miracle and let Newton’s sacred soul balance the restoring force of the pendulum.
Newton’s force will be classified by future historians in the same category as that silverware bending force. Professional physicists who see visions of Newton’s Soul moving pendulum arms will be classified as professional charlatans.
