Action and Reaction - I. Newton

Hi,

I have for me a complex question! :(

If I get to Mt. Everest (let's say - highest place on Earth), then there is acceleration of my body towards the Earth - because of g - gravity force.

Now - question is does Earth have acceleration towards my body - as 3rd Isaac N. law would say!

And if it has - why?

Thanks for help

Yes. The difference being, the acceleration on the Earth is negligible. Let's take f=ma, you exert, say, 800N (i.e. 80kg * 9.8ms-2) downwards. Likewise, the Earth now has a force 800N acting upwards. But, since that 800N is acting on 238083259285928234523kg of mass, the acceleration is just too small for anyone to care.

Maybe when global warming dies off, we'll move onto "global acceleration"?

Good one! Thanks for AW.
