Physics:) help?

Question

ok ive already posted a question about wat to put into my conclusion and stuff (thanx for the gud answers) but now im stuck i have to compare my result with the theoretical value of g= 9.81 m/s², my personal result came to 7.6m/s^2... how can i compare them?

If you dont know or havnt seen my other posted question this is the experimant we did,


1. equipment was set up

2.One group member held the top of the ticker tape with mass just beneath the ticker timer

3.The tape was then released, allowing the tape to move through the ticker timer as the mass fell into the bucket below

4.The tape was then labeled with one of the group members names

5.Step 1-4 were repeated until each group member had an accurate record on tape

(The aim of the experiment is to measure a ticker timer to measure the acceleration due to gravity.)

ive done the conclusion and everything else just not the comparing bit...?

some1 said that you have to do this -
[7.6- 9.81| / 9.81] x 100%

Answer 1

thats right thats how u do it

Answer 3

I'm not fully acquainted with the experiment, but it may well be the nature of the beast to get a result like you did. The equation you supply is the percent deviation from the expected value, which is an accepted method of summarizing results.

Answer 4

so ap physics is in simple terms particularly stressful, and as constantly relies upon on the instructor besides (is he/she a sturdy instructor? lots or little artwork, and so on...) additionally relies upon on what else you're taking once you're taking ap physics, if the different training are not stressful and you will concentration on the class, then it relies upon and it relies upon on you, and how the priority is for you, and how stressful you prefer to artwork at it sorry if this would not help, yet there are assorted factors...
