Can 'forzar' ever mean the same as 'obligar'?
In some contexts, they can be very close, especially when talking about circumstances. 'Las circunstancias me obligaron/forzaron a cambiar de opinión' (The circumstances forced me to change my opinion) are both used. However, 'obligar' is generally preferred as it sounds more natural.

It often has a negative or aggressive feeling because it implies going against something's will or natural state. However, it can be neutral, like 'forzar la vista' (to strain one's eyes) or 'forzar una cerradura' (to force a lock), where it just describes a physical action.
