What is this
This drawing is intended for understanding the force of friction
If a boy slides down the slide
His pants come off
The loss of his pants demonstrates
the force of friction
This force is exerted in the direction opposite of the motion
That's easy to understand
In textbooks
it's explained in this manner
Things like these are not easy to remember
and you'll forget it right away
