Does anyone know of an experiment to measure the value for gravity's acceleration???

Hello to all the physics students out there!

Does anyone know of an experiment (apart from the pendulum one) , to measure the gravitational acceleration?

er... rolling a ball down a ramp and ticker timer exp

 

[gordo]

pendulum exp

how would i find 'g' with the ticker timer?

 

[sikeveo]

by looking at the difference in gaps between the dots and then calculating g

If you have a stroboscope at your school use it, ask your teacher if your school has one. It makes quick flashes at equal intervals and you can analyse the horizontal and vertical motion and hence calculate g.

thank you!!! =]

use carbon paper for rolling a paper down a graph paper

Dropping an object from a set height and timing it.

pendulum is the easiest and most accurate by far i reckon...

ok, you swing a pendulum through less than 10 degrees and then use the formula:

g = (4pi^2)/T

ta da!

u missed the 'length'

The pendulum experiment is also the one in the syllabus.

Yeah I have as well. It is the one we used as it was the one as a syllabus dot-point.

The issue with the pendulum experiment is that it is in the syllabus. This means that if you are trying to use this experiment for an open ended investigation as an assessment for the HSC then you cannot. This is because for an experiment to be considered you are not meant to know the outcome, if you have formally covered the experiment, as per the syllabs then you know the outcome and it cannot be used.

However that is a formality, if you need to do an experiment that relates to 'g' and have done one in Yr 10, you can still use your experiment from year 10 and amp it up to a HSC standard, even if you know the outcome. THis is because as far as the Board of Studies are concerned you haven't covered in in your syllabus, and thus don't know the outcome.

well that's how it works where I'm from. I'm pretty sure it is the same everywhere.
