Energy flow characteristics of vector X-Waves
The vector form of X-Waves is obtained as a superposition of transverse electric and transverse magnetic polarized field components. It is shown that the signs of all components of the Poynting

Force due to velocity
It's more than just wording, shamrock, and we're just trying to be helpful. Some of the issues:
is there a way to calculate the force that an object will exert when it is moving at a certain velocity... force equals mass times acceleration, but if an object is travelling at a high rate of speed

Calculus Course/Sequence
In mathematics, a sequence is an ordered list of objects (or events). Like a set, it contains members (also called elements or terms), and the number of terms (possibly infinite) is called the length
of the sequence.

Precalculus - A Fuctional Approach to Graphing and Problem Solving
• A rational function f is the quotient of polynomial functions defined by
P(x) and D(x) so that
f (x) = P(x)/D(x) where D(x) does not equal 0
