how we can calculate error in an experiment?

Question

for example while calculating accelaration due to gravity using simple pendulum,initially we assume that nobody knows the value of accelaration due to gravity.tat is we are the first person doing that experiment,then how we can calculate error in that experiment?

Answer 1

I think U should go for 11th std. physics book. It will explain deeply about error in your experiment............

Answer 2

For calculating the error in this experiment use the following rules
1)Find the rlative error for evry value in experiment.
2)add up thm for every multiplication and division
3)multiply the error wit the power (only for those which have)

Answer 3

as good as i am in physics, i just didnt try to understand error calculation
can someone give me 2 easy ways to calculate
error in addition

for example

5 +- 0.2 + 6 +- 0.1

and in mulitplication, like my newest lab
i have f = m tiems g
and the mass is +- 0.2 and gravity is +- 0.1 for example
mas is 25 g lets say, and gravity 9.8


so ya easiest way to calculate error in multi, and additio please :)
thanks

Answer 4

u shud try 2 follow da instructions carefully.
