Rocket Launch & Projectile motion Analyzed with VideoPhysics App
Download the following Apps to your phone or pad
Video Physics (video analysis)
Inclinometer
Motion-X GPS
Wind Speed (annemometer)
AccelMeter (accelerometer)
Record Data
Position the rocket launcher so that it is pointed vertically. Check using your inclinometer app in your mobile phone
Record the windseed using your mobile wind spee App
Record your precise GPS location using the GPS App
Using your accelerometer App in your mobile device, determine the maximum acceleration obtained by jerking your device quickly. Record in the table. By doing a video analysis of the rocket you can determine its acceleration and compare with your tests on your mobiel device.
