When the ball from the other device falls into the cup car's cup, the cup car descends.

'Cup Car' 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.
