Electrostatic Induction
In this video Paul Andersen explains how the charge distribution can be affected my electric forces produced by a charged object. In an insulator charges are fixed but in conductors the charges can move. Induction occurs when the charges...

Understanding Electric Charge and Friction
This video explains the concept of electric charge and how it can be transferred through friction. It demonstrates how a balloon, when rubbed against a person's head, gains a negative charge and attracts positive charges in the wall....

Atomic Masses and Composition of Nucleus
This nugget describes the nucleus of an atom. It talks about the various aspects of a nucleus like atomic number, atomic mass unit, isotopes and isobars, with examples.
Flipping Physics
Polarization of Charge
Three demonstrations of polarization of charge are shown. A balloon polarizes a wall, small pieces of paper, and an aluminum can. The difference between conducting and inducting materials is presented.
Flipping Physics
Charging by Conduction and Induction
Charging by Conduction and Induction are both demonstrated. Each individual step is clearly described. Electrical Ground is introduced and defined. Both demonstrations are illustrated.
