In our daily lives, there is a coin-sorting
machine that also uses the same principle as
the gravity-pick machine. Inside of the machine
is a sloped-spiral track. After inserting coins,
the coins travel down along the sloped track in a circular
motion. On the sides of the track are several round holes
that differ according to each coins’ diameter. While the coin is spinning, a
centrifugal force is created. Therefore, when the size of a coin matches
a hole’s size, the coin will be sucked out into that hole by its centrifugal
force, and will fall into the container. Since only coins of the same size
would be collected in each container, the machine can successfully sort
out different coins from one another.

In 17th century Britain, a person designed a perpetual motion machine. The
machine they designed consisted of a turntable with many inclined partitions.
Dozens of steel balls rotate in a circular motion along with the turntable, which
increases their torque. When a steel ball reaches the top point of the machine,
the ball would roll back to the turntable center along the inclined surface. The
ball would then once again follow the turntable
in a circular motion, increasing its torque
accordingly. The turntable rotates from this
repetitive movement, making this a perpetual
motion machine.
Kids, after understanding this principle can you
build a gravity-pick machine?
