Hello, I am doing a physics exam, where I have chosen to create a Brachistochrone curve, and perform various tests on it. Furthermore, I also have to write a physics report, containing the theory behind the curve, but I am not 100% sure what some of the theories behind the curve are. I suppose...

Okay, that makes somewhat more sense! Thank you.

Okay, so I get that if you let r -> 0, the force of gravity will by definition become infinite. My question here is, what does it mean when the force of gravity becomes infinite in this sense?

Hello! I'm doing a school project, where I am writing about Infinity in Math and Physics. I've got the math part settled, but it's the physics part that has begun to bother me. One part of my task is to write about some of the mathematical expressions in physics, where we use infinity - but the...
