1E10.15 Moving Blackboard

Using a large movable reference frame on wheels and a walking student, equations of relative speed can be deduced by non science  majors.

.A small blackboard is clamped vertically to a rolling cart. A large meter stick, marked in yellow and white sections for better visibility, is fastened to the top of the blackboard. A tall man with glasses (Vacek) stands at one side of the blackboard. His right hand holds a piece of chalk that marks a horizontal line across the blackboard as the blackboard is pushed along. The entire demo is photographed against a white background.

Movable chalkboard to observe relative speed to make equations.
