Electrostatics
Terms & Objectives
The Indiana Physics Standards that Relate to Chapter 32 - Electrostatics are:
- The Properties of Matter
- P. 1.1 Describe matter in terms of its fundamental constituents, and be able to differentiate among those constituents.
- P.1.2 Measure or determine the physical quantities including ... charge....
- P.1.4 Employ correct units in describing common physical quantities.
- The Relationships Between Motion and Force
- P.1.10 Demonstrate an understanding of the inverse square nature of gravitational and electrostatic forces.
- The Nature of Electricity and Magnetism
- P.1.17 Describe the interaction between stationary charges using Coulomb's Law....
- P.1.18 Explain the concept of electric charge, ... Use the definition of the coulomb...
- The Nature of Atomic and Subatomic Physics
- P.1.29 Describe the nuclear model of the atom in terms of mass and spatial relationships of tle electrons, protons, and neutrons.
- P.1.30 Explain that the nucleus, although it contains nearly all of the mass of the atom, occupies less than the proportion of the solar system occupied by the Sun. Explain that the mass of a neutron or a proton is about 2000 times greater than the mass of an electron.
- P.1.31 Explain the role of the strong nuclear force in binding matter together.

Electrostatics Objectives:
When you finish your study of electrostatics, you should be able
to:
- define electrostatics.
- give evidence for the existence of two kinds of electric
charge (like charges repel, unlike charges attract).
- describe and demonstrate a method for determining whether an
unknown charge is positive or negative.
- name the unit of charge, and discuss its size with respect to
common electrostatic situations and in terms of the number of unit
charges it represents.
- describe what it means to say that charge is conserved.
- in terms of protons and electrons, describe a:
- neutral atom
- positive ion
- negative ion
- electric, atomic & nuclear forces:
- discuss the role of the electric force inside the
atom and between atoms.
- tell what the strong force does, and compare it to the
electric force.
- state Coulomb's Law and compare/contrast it with Newton's
Law of Universal Gravitation.
- compare and contrast the electric and gravitational
forces.
- use Coulomb's Law to tell what happens to the electric
force between two objects when their charges or relative
distances change.
- describe the electrical properties of:
- conductors
- insulators
- semiconductors
- superconductors
- describe, in terms of the movement of charges, how an object
can be charged by:
- friction
- contact
- tell what grounding is and describe how it works.
