Electricity
Kepler's laws
Impact
and Gravity Simulator
This is a little java program simulating the
interactions of balls. You can grab the balls with your mouse and drag
them or throw them. You can control the friction and gravity. You can make
the walls be bouncy, or wrap-around. You can simulate planetary systems,
rubber balls, Brownian motion, pool table physics, and more.
Kepler's
laws of planetary motion
This page provides brief description on the discovery
of the Kepler's laws. It has links to three separate pages demonstrating
each of the Kepler's laws using both the qualitative and quantitative methods.
Circular,
Satellite and Rotational Motion
This gif animation provides several different
basic descriptions on the Kepler's laws of Planetary Motion.

Charges
This applet allows us to see in a graphical way
concepts like electric and potential fields.
In this program, the players can move, erase
or place an static charge. The amount of charge can also be adjusted. Besides,
the players can also choose different form of the animation display.

OHMS
LAW: Activate the Light Bulb
This java applet examines the Ohm's law by a
light bulb circuit. The animation provides a light bulb with fixed
ampere value and it allows the players to change the value of the voltage
supply. After the voltage is chosen, the students are required to add the
resistances to the circuit in order for the light bulb to glow. The basic
theory of the dc circuit is also provided.
Ohm's
law
This simulation shows the current in a
circuit. After entering the value of voltage supply, the resistance of
the circuit and the bulb, the power dissipated and the current in the circuit
are calculated. Quantitative and the qualitative treatments are shown
and a quiz with solutions are provided.
Measure
voltage and current in a Wheatstone Bridge
The Wheatstone Bridge is used to determine the
unknown resistance in a circuit by adjusting a known resistance. This java
applet demonstrates how the Wheatstone Bridge works and the players can
measure voltage and current at any places in the circuit. It also allows
the user to enter the values of the resistance and calculate the unknown
resistance with the answer checked by the progamme.

This page provides the description of the Biot-Savart
Law and using a java applet program to demonstrate the relationship between
the magnetic field and the current.
