Part II
In Which
We Apply Our Knowledge of Field
Forces to Gravity We can now study some problems
involving gravity using what we have learned about field forces. In particular, we will study how massive
objects orbit each other.

|
What you need to know and understand: q Energy in Orbits q Orbit shapes as conic
sections q Escape velocity |

Part III
In Which
We Apply Our Knowledge of Field Forces to Electricity Much of modern technology runs on applications involving
electricity and what we have learned about field forces. We will study applications involving both
static electricity and electric current.
Static electricity is used in copies & laser printers, air
filtration systems, and other technologies.
Static electricity can also be a
unpredictable hazard. Electric current
is used in all sorts of technology from electric lights to motors to
amplifiers.

What you need to know and understand: q Irrelevance of motion
of positive vs. negative charges. q Conductors in
electrostatic equilibrium. q Grounding and
Induction. q Flux and Gauss’s Law. q Voltaic Cells &
Batteries q Capacitors q Energy stored in a
Capacitor q Electric Current &
Ohm’s Law q Power and Current q Kirchoff’s Common-Sense Rules |

Part IV
In Which We Discuss Magnetism Magnetism is a complex subject full of counter-intuitive
notions that make magnetic phenomena sometimes seem almost
"magical" in the same way that certain rotational phenomena seem
almost magical. We will focus first on the production of magnetic fields by
moving charges and magnetic attraction/repulsion. We will then discuss the
topic of induction – an important topic that has many applications and that
leads to the concept of electromagnetic waves. Our discussion of magnetism
will be somewhat "descriptive" and will involve "thought
problems" rather than being "calculational"
and involving "math problems".
