Course Description

This is less a Physics course and more a collection of resources to accompany the Physics and Honors Physics courses taught at Divine Child High School. I will be adding to this course throughout the coming school years.

The cover image was created by Jack Mazur. 
The picture is a simple demonstration of an object's inertia, in this case, the object is a little man. This poor little man is sitting on top of a moving train and the train crashes into a wall that is in its way. This man is not strapped in to his seat, therefore, he has nothing to stop him as he continues forward, no force acting on him to change his motion. A second, less apparent force acting in this picture is a push force from the train on the wall. Due to the wall's mass, which is great in comparison to the train, the train is unable to exert sufficient force to move the wall, hence the sudden stop, causing the man to continue moving forward. Of course, there is also gravity force acting on both the man and the train, and normal force acting from Earth to train and train to man.

Outstanding Course

Outstanding course material. Even a grown man at 45 can learn from this. Very great refresher on lessons learned from years ago. Thank you for the presentation.
