The actual motion of the line has many possibilities.

The differences between the Keplerian orbit and the actual motion of the body are caused by perturbations.

The purpose of the statistical function is to remove matches that do not correspond to the actual motion.

Neither of these are ideal to give a good impression of the actual motion happening in the sequence.

Convection - Here energy is transported by actual motion of the medium.

"Since we left the Sky Queen, we're covered only about a mile in actual forward motion."

Increasing flight hours is also an issue for pilots as they become more accustomed to the actual motion in a vehicle.

The effect is similar to overcranking as the actual motion occurs over a longer time.

I'm assuming the actual motion of the tendrils does not in itself generate these frequencies.

In neither place is actual motion intended to be expressed.
