This only makes sense in a relativistic context, but forces don't exist in relativistic contexts.
So you can either have F = ma, or you can have GR, but you don't get to have both at the same time.
- selimthegrim 7y agoWait, you can’t write the Lorentz force down?

- pdonis 7y ago> forces don't exist in relativistic contexts Yes, they do; the difference in General Relativity is that gravity is not a force, but non-gravitational forces are still there.
