'Twister Switch' Principle of Science
Gravity : The force by which objects on the earth are drawn toward the center of the earth.
Inertia : The force by which objects on the earth are drawn toward the center of the earth.
Potential energy by gravity : The property of an object trying to continue in a state of stationary or constant motion unless it is subject to external forces.
Centrifugal force : The force that acts from the center to the outside when an object performs a circular motion.
Pendulum movement: A fixed hanging object under the influence of gravity moves in a constant cycle.
