A2 practical: Flying pig
In this practical the acceleration due to gravity will be found by measuring the time period of a pig flying in a circle. Note: this experiment can also be done with flying cows, dinosaurs and even planes. (With acknowledgement to Mark Headlee UWC USA) The pig flies in a circle because there is a force acting perpendicular to its velocity (towards the centre of the circle). This force can be identified by drawing a...
