Audacity+99

99 Things to do with Audacity.

Perhaps 99 is a bit hopeful but ......


 * 1) Speed of sound in air
 * 2) Speed of sound through a lab table
 * 3) Speed of sound through jelly (I will do it one day, honest)
 * 4) Measuring time interval between bounces of a ball
 * 5) Measuring speed of dropping magnet in a burette tube
 * 6) rolling a spherical neomagnet down a ramp and measuring speed
 * 7) Measuring speed of ball bearings fired by a Gaussian gun
 * 8) time period of a pendulum (neomagnet on a string)
 * 9) seismograph
 * 10) speed and acceleration of a toy car down a guttering ramp
 * 11) spherical neomagnet a roller coaster made of clear plastic tubing (speed, KE and GPE)
 * 12) conservation of momentum with neos stuck to mechanics trolleys/air track carts
 * 13) I've made a working wind turbine, which is just the coolest thing and generate AC (Vid below) JF
 * 14) [[file:Complex wave forms -- audacity.docx]] [[file:Complex waves XL.xlsx]]something I picked up from my sixth form placement turning sine waves into square ones - is this useful?
 * 15) A2 Coursework - one of the students hit a metal rod holding it in the middle, then recorded the sound with audacity. He then identified the harmonics. he then supported the rod in 2 places and repeated it to get further harmonics
