Measurement of Gravity

Hello

I am a newbie to 'Gravity Measurement'.

This might sound a bit stupid, but can I measure 'Gravity' in my home?

Please advise.

Thanks.

There, done it for you 9.807 m/s²

that's an average. Gravity on the Earth's surface varies by around 0.7%, from 9.7639 m/s2 on the Nevado Huascarán mountain in Peru to 9.8337 m/s2 at the surface of the Arctic Ocean.[5] In large cities, it ranges from 9.7806[6] in Kuala Lumpur, Mexico City, and Singapore to 9.825 in Oslo and Helsinki.

(thanks to wikipedia)

Yes. See: Cavendish Experiment

I am in Mumbai, India.

Thank You. I will try doing this.

you'll have to measure it.. it's tricky :slight_smile:

may be the GRACE project has public data

What did you do? :slight_smile:

You must live on an asteroid.

OP wants to measure Gravity and NOT the "acceleration due to gravity". Are they same?

Ask Einstein. :slight_smile:

Einstein has learned it from Physics?

Imagine you're in a spaceship accellerating at 9.8m/s/s. What do you experience? :slight_smile:

Any simple example with our everyday events like the falling of an apple on the ground?

I have my own planet

If you want to differentiate acceleration and gravity, you need to define them very well.

Also you can't measure something abstract without the use of a real device, e.g. you can't measure length without a ruler-like device. When you use it, you are not measuring rulers or "things", you are measuring length.

In the same way, measuring acceleration is a way to measure gravity. The only other way is to measure weight, i.e. the strong force interactions that support a standing object, like an apple sitting on a table. But the problem there is variable mass, apples and other objects have different mass. If you let them fall, that problem is eliminated.

Galileo, Galileo!

The definitions are there in the Physics book?

You can find these videos helpful:

Last time I looked, yes. But it was around 1995 I guess. Maybe gravity has changed since then. Lots of other things have. :slight_smile:
