Physics JAVA applets |
| |
On your home computer,
go to
http://www.walter-fendt.de/download/ph14dl.htm or use the direct
links below to download the zip file containing Physics JAVA applets
created by
Walter Fendt |
| a) |
Download the JAVA applet
simulation library to your computer |
| |
Right click on File name and select
Save target as... (IE) or Save link as...
(firefox) to save to your hard
(the (e)nglish and/or (s)panish version |
| |
| Language |

| English |
ph14e.zip |
500 KB |
ph14, ph14_gifs, ph14_jar, ph14e |
| Español
|
ph14s.zip |
514 KB |
ph14_gifs, ph14_jar, ph14s |
|
| b) |
Install the applets on your hard
drive |
| |
Create a folder for the contents of
the zip file. (i.e. physics_simulations) |
| |
Extractz the contents of
the zip file into that folder |
| |
Go to that folder and verify that the
following folders have been extracted |
| |
ph14
ph14_gifs
ph14_jar
ph14e (or ph14s) |
| e) |
Run the JAVA applet |
| |
Go to the
ph14e(or s) folder |
| |
View the file
timedilation.htm
using your WEB browserb |
| |
Run the simulation using speed of
.5C |
| |
Change the parameters and re-run
using .8C .9C and .99C |
| f) |
Print out the page or do a screen
capturesc of
your simulation |
| g) |
Try out one or more of the
following applets (find one that works) and save a screen capturesc
of it |
| |
|
| h) |
Post a response to the
simulations forum on the newsgroup |
| |
Go to the newsgroup and post a reply
to time dilation posting |
| |
open the Simulations forum |
| |
post a reply under the simulations
forum to the Time Dilation JAVA applet
message, include the time differentials for each speed run |
| i) |
Print out copies of your screen
capturessc to turn-in in class |
| j) |
OPTIONAL:
Try to find some other simulations on your own. Use Twin Paradox or
Time Dilation in your search. Refine your search with Applet
or JAVA or
Simulation |
| |
footnotes |
| b |
Open file using your WEB browser,
Internet Explore 6 is best but IE5 will work, some simulations will
work on Netscape or FireFox but are inconsistent and may lock up
computer |
| sc |
Screen Captures are best done
with a program like Screen Print and Capture 32 , Snag-it
(Windows) or Snapz-Pro (Mac) |

The Earth's curvature results in a vertical distance of 4.9m for every
8,000m tangent to the surface
Try these numbers out in the

Projectile Orbit
Alter the tangential velocity and watch what kind of orbit results
Earth, Moon and Sun
http://observe.arc.nasa.gov/nasa/education/reference/orbits/orbit1.html
Try out this simulation from NASA of a satellite in an elliptical orbit,
change the eccentricity of the orbit and see the results. Watch out or you
might crash the satellite into the Earth!

of Arizona, Tucson VERY VERY EXTENSIVE. "...will estimate the seismic,
blast wave, and thermal effects of an impact as well as the size of the crater
produced by the impact..." For more information see

better yet, in moon orbit
