project on newton's laws of gravity

[siddhu_bansal]

i need some help preparing for a project based on newton's laws of gravity!!!!!

It sounds like you need help choosing a topic.
Do you have any ideas for a project that you'd like to do? What interests you about gravity?

My suggestion would be to begin by reading about gravity. Some questions to think about: Is gravity the same all over the surface of the Earth? How does one measure gravity. Design a gravity-measurement device that a student might build, for example a simplified version of a commercial gravity measurement apparatus. Before building the device, calculate the potential accuracy of the device by analyzing the various sources of measurement error. Build the device and measure gravityd. Compare your results with the official numbers (from the USGS). Are your measurement within your calculated error bounds? If not, can you suggest why not?

If you go with paulsdecarli's idea then here is a sight that talks about measuring gravity:

1. http://adelie.harvard.edu/ed/Activities ... avity.html

Here are some other topics:
1. How does gravity assist with interplanetary satellites?
2. Where do bullets go when fired straight up into the air? (i'm not sure if this meets the requiremnts for your topic)

I hope this helps!

Ah, now here is a topic that I might be able to provide some assistance with! In my line of work, we occasionally get asked the very question that Jessica just posted ("2. Where do bullets go when fired straight up into the air?").

If you want to pursue this topic, please just let us know!

Good luck,
Geoff.
