### Why should Conservative forces have their curl equal to zero?(intuition)

"Curl" is a pretty well named mathematical term--it denotes the degree of "rotation" in the vector field. For this reason, if you go all the way around in a vector field, you'll find that the total ...

### What exactly makes a force conservative?

All fundamental forces are conservatives and I would say that this is a postulate. Fundamental physics is constructed in such way that there is a quantity called energy which can be assigned to every ...

### How can you conclude that gravity is a conservative force?

Are you looking for a mathematical proof (which has been given by others), or an experimental demonstration? If gravity is not conservative then that means there would two paths up a mountain that ...

### What is a potential?

Electric potential and electric potential energy are two different concepts but they are closely related to each other. Consider an electric charge $q_1$ at some point $P$ near charge $q_2$ (assume ...

### Is gravitational energy always conserved?

so net work done would be 0 Net work of all forces is 0, and that is why kinetic energy of the body does not change - it remains 0. This is an example of the general theorem \text{work of all ...

A constant force is conservative but not central. For example: $\vec F=F \hat x$ You can check that the curl of this force is $0$, hence it is conservative. Its potential energy function in 3D space ...
