I know basically zilch about physics so this may seem like a really stupid/obvious question, but why do we refer to a field as a force field? Is it simply because a particle experiences a force in that field, or is it because there's more than one 'type' of field?

Well, force fields are a type of vector field so named because a particle in them experiences a force, so you're right on both counts

In general a field in physics is just a quantity which takes a value at every point in space and time. There are many types of fields, electric and magnetic fields, temperature fields, force fields, quantum fields etc.

Why the word 'field'? Don't know, that's just what Faraday decided around 1850 to call such things and people liked it.

Oh I see, thank you for putting things into perspective! Never heard about temperature fields before Wouldn't electric and magnetic fields also be classified as force fields though? Or do 'force fields' apply to gravitational fields only?

The term force is the big clue.

If the object or particle experiences a force to change it's state of rest or momentum, then it is within the 'field' of influence of whatever that force is.

The four fundamental forces projected at a distance are: gravitation, electromagnetic, strong nuclear and weak nuclear forces.
