I was taught Newtonian physics. I use it regularly and successfully in engineering on earth. It is extremely difficult to grasp the theories of Einstein. Perhaps astrophysics is where it is better used.

This is why I question the practicality of GR on earth. Perhaps its because I haven't studied GR in depth but I cannot grasp the 2 previous Einstein statements. They directly contradict Newton which is what I was taught in motion physics. A body at rest has a velocity that remains at zero...

I did mention in my opening paragraph to excuse any incorrect terminology. I know what ur saying. Thanks again to all

Ah yes I was going to state that there wouldn't be anything to learn really. It would just b a cool scaled down experiment to observe I feel. GR is definitely for larger bodies at greater speeds over larger distances

@Phinds What do u mean by "a limited case" I agree Newtons equations of gravity and motion are much easier and more applicable to everyday science and engineering on earth. His equations are still being used everywhere in everyday applications. GR is much harder to grasp and is really used in...

@A.T. Very interesting animation. So GR does in fact apply in Earth's atmosphere also. Thank you for answering one of my questions. Lol. What a freak of nature Albert Einstein. So much perseverance the man had also. I shouldn't have titled this Einstein vs Newton. I wanted to compare the two...

Thanks to everyone for the feed back. @ModsPwnd. I understand their testing gravitational forces of bodies. Not the Earth's gravity. I just imagine putting a large mass which represents Earth in a vacuum chamber. Test its gravitational pull on a small object representing a car. No strings...

Excellent. I believe the experiment was done under Earth's gravity. Have other experiments been performed in vacuum enclosure? I would like to see a huge suspended mass with a tiny object pinned to the bottom by gravity. To simulate myself standing upside down in Australia

What a genius Isaac Newton really was. He blows my mind So has this practical example been performed and confirmed?

Hi my background is in mechanical engineering. I use a little bit of motion physics but not often. Pls excuse any errors or wrong terminology I may use. Einstein's theory of relativity addresses the force of gravity in space time but does it address or apply to gravity on Earth? What creates...
