-By taking a video of a freely falling object and processing it so that we can see the position of the object in each frame (which at 30 frames per second is every 0.033 seconds) we can analysis ​the motion of the object. The tool to do this is [[http://​www.ic.sunysb.edu/​class/​phy141md/​videoanalysis/​verticaldrop.html|here]]. ​+By taking a video of a freely falling object and processing it so that we can see the position of the object in each frame (which at 30 frames per second is every 0.033 seconds) we can analyze ​the motion of the object.

 As well as using video frames as we did it is also possible to use sound to measure the time taken for objects to fall. This approach is nicely illustrated at [[http://​www.animations.physics.unsw.edu.au/​mechanics/​chapter2_projectiles.html|Physclips]] (Section 2.2) As well as using video frames as we did it is also possible to use sound to measure the time taken for objects to fall.
