Yes! It is the fact that we can explain gravitational fields in a more fundamental way than the electric field. The two are so similar mathematically, I wasn't sure if there was an equivalent deep explanation for Electric fields.

haha! I often confuse myself by asking strange questions like these that perhaps don't make complete sense. It drives my teachers mad. It's great

But for gravity we know that the force that causes the attraction is really just the warped space-time, so I can easily accept what is happening between the masses that causes the attraction. However, with electric fields, there is nothing physical that is happening between these charges. What...

I have just covered the electricity unit in my advanced higher physics course, and have happily accepted that a force is created between charged particles. I understand that coulombs law can be used to calculate this force, but here is my question. What actually is this force between the charged...

Is this the correct derivation?

Once the experiment is set up correctly would the equation to find Young’s modulus be y=(4mgl^3)/(bd^3 δ) and if so, how do I derive this?

I have a question regarding finding the Young’s modulus of a rod by loading a weight to the end and measuring the change in displacement. The experiment is part of my advanced higher physics project on Young’s modulus however it is the only experiment that I’m doing that the book “Tyler” does...

I am currently 16 and from Scotland. I plan on completing a masters in physics once I go to university, however I am now starting to wonder what fields of physics are the best to go into. My preference would be to do research, which leads to my other question of how possible is it to have a...

Thank you, I have asked a few people with a more physics related background to myself but they weren't too sure. This clears everything up.

Thank you very much, very helpful

If an object is in a large vacuum chamber and is dropped, what is to stop it from accelerating to the point that it passes the speed of light, because there would be no air resistance to stop it from constantly accelerating?
