Centrifugal force

Centrifugal force is a concept in Newtonian physics that is essential to the delicate balance held together between it and the gravitational pull of the planets in the solar system.

Von Knowalot demonstrated to the Super Friends that if such a balance were to be disrupted, it could cause the Earth to fall from its' orbit. Which is what had happened due to a magnetic wave caused by Kolbar, to draw the planet closer to the sun.
