Practical - Freefall

Aiming for a value of 9.81, this experiment allows you to see the effects of errors in your measurements.

 

1. Calculating 'g' with a Freefall Method

Dropping a steel ball bearing through light gates can be used to find the acceleration due to gravity. Recording the time taken for it to fall as you then change the distance between the gates allows a graph to be plotted the the value of 'g' determined.
