Position, Velocity, Acceleration Graphs - Online Resources

-
I know that the study of kinematics for position, velocity and acceleration is very basic. But it is so important.

Believe it or not, some study I have been doing on space/time led me to look very carefully at just what distance and time are. It was so vital that I grasp deeply their relationship that I was led back to review basic kinematics.

Incidentally, basic calculus is not hard at all. It is very simple and easy and it is a shame that somehow it is taught so that many people never really get it or enjoy it

That is why I think the quickest way for the student to grasp and get and enjoy calculus is through the basic position (displacement) over time, velocity over time, and acceleration over time graphs, and how easy it is to understand differentiation to get velocity and again to get acceleration, and then integrate to go backwards.

So, for starters here are a couple of good places to learn the graphs online

The physics classroom.  Here is a clever animation of position, velocity and acceleration graphs

You will find links to the lessons for this animation.

Mrs. Twu has made excellent videos. She is super smart and moves quickly but covers the material thoroughly. I highly recommend her videos.

Here for example is one of her videos on motion.   We are lucky to have an outstanding person like her to share her knowledge with us.

My Child Will Not Do Her Homework

So many parents get so bogged down in the homework issue that they forget about the most important thing of all: the relationship. Relating to your child with love and understanding is a million times more important than any particular homework assignment. . How much homework did Einstein do? Who knows? Who cares? He did not do very well in school. So instead of homework, he was probably doodling and daydreaming. Does your child doodle and daydream? Maybe he or she is another Einstein. . Many people do not know that when Mozart was a kid, his dad took him on several long trips. His dad intuitively knew that music was important to his son. He took his little son to major music centers so that he could meet composers, perform, attend concerts and see operas. One trip, when Mozart was 7 years old lasted 3 years! He and his dad visited all the major music centers of Western Europe. . Another trip, when he was 11 years old, lasted 15 months. He got to meet Johann Christian Bac...

Pastor Speaks Out Against Spanking and Child Abuse

"Should parents spank their kids? " Absolutely not," says Roland Trujillo, pastor, lecturer, and author of 17 books. "It is totally unnecessary."   "For 25 plus years I have advocated against spanking. What does spanking accomplish? It introduces the child to fear, to trauma, and often to rage. It turns some children into fearful conformists, and others into rebels because of their hatred of the parent who used violence on them.  Spanking is often a euphemism for something much worse. Inflicting harm on an innocent defenseless child is despicable. It is bullying--the evidence of a tyrant, a large person hurting a small person. It is evidence of lack of patience, kindness, gentleness, self control, forbearance, and wisdom. It is a massive betrayal.  Here are two things that need to be stated. Child abuse is a little known contributing factor to violence against women. The male child who is beaten, slapped, spanked, yelled at, teased, or verbally...
