Please could you write up the practical work done today. this needs to be recorded in your books. 

remember little things like the date, units, sig figs etc.

what I am expecting:

1. tennis ball.

brief outline of process, results table, calculation of g.

brief answers to questions asked on instruction sheet.

calculation of % error in g vs 9.81.

2. trap door

brief outline of process, results table, graph of s vs t^2 and gradient.

calculation of % error in g vs 9.81.

error analysis - now for this you need to estimate the % uncertainty in your method. this will require assumptions and some subjective thought. ie, which values of t and s do you use to represent your experiment. you should comment on such decisions.

Please ask if you need any help.

Cheers

Mr Clarke
