Glass rods, plastic tubes, silk, and fur can be used to demonstrate the
movement of electrons and how their presence or absence make for
powerful forces of attraction and repulsion.
A train covers 60 miles between 2 p.m. and 4 p.m. How fast was it
going at 3 p.m.?
The speed is traveled distance (60 miles) divided by traveled time
