Hey, squirrel! Hey, Squirrel!
Do a handspring! ♬
Because it holds the center
of gravity with its tail.
Center of gravity?
Look at the squirrel sitting on the tree!
It's so stable without falling!
It is the unique point at the center of a
distribution of mass in space.
Look at the giraffe drinking water!
And his posture is a little...
Giraffe has a long and heavy head, so it could
fall down while drinking.
So not to fall, giraffe holds up the
body with four legs.
There is a center of gravity inside of
our body as well!
We can stand up more stable when we
open our arms and legs.
Ah~ Not easy to stand
on one leg.
There is a center of gravity in our
belly button!
We don't fall down when the side of
mass is the same for both sides!
