Here are links to videos that explain and give examples about the concepts we are learning in Chapter 20
FINDING THE EQUATION OF A TANGENT
This video goes through an example of finding the equation of a tangent to a curve.

KINEMATICS
This video goes goes through all the concepts of position, velocity and acceleration
https://www.youtube.com/watch?v=UxYwLcZwJCs

This video also goes through the basic concepts with an example
https://www.youtube.com/watch?v=pFeuGMMiZWw

This video goes through the concept of distance (as opposed to displacement)
https://www.youtube.com/watch?t=65&v=HDntI7zfBNs

This video goes through when a particle is speeding up, and is really good for enhancing your understanding of these concepts

STATIONARY POINTS
This video explains how to find stationary points on a curve
https://www.youtube.com/watch?v=JawmTELoX2U

This video goes through another example on finding stationary points (sometimes called "CRITICAL" points in some videos)
https://www.youtube.com/watch?v=H-XDX7T0ADw

This video goes through how to determine the nature of the stationary point
https://www.youtube.com/watch?v=HMhmC9rLzew

This video goes through a very thorough example of determining the nature of the stationary points using the sign of the derivative

INCREASING AND DECREASING FUNCTIONS
This video goes over the concept of increasing and decreasing functions, which we learned in Ch 19 but is crucial for understanding the Sign of the Derivative Test for stationary points.

MAX/MIN (OPTIMIZATION) PROBLEMS
This video is an excellent introduction to Max/Min (Optimization problems), and goes through all the steps in detail. 
https://www.youtube.com/watch?t=928&v=GQGB5hhE61Y

 This video explains the steps involved in solving Max/min (Optimization) problems. Watch first example only (up to 7:11)
