Or how we pronounce it in Japanese, " 慣性 " (Kansei)
Inertia is the resistance of the object to any change in its motion, including a change in direction.
We will stay the same or keep moving at the same velocity and in an unwind line,unless an external,unbalanced power acted upon us.
Be part of our energy circle and together we move undisturbed.
ありがとう Arigatō.
