Hi, I'm not sure what tension refers to in f=ma questions? is it literally just the forces in the direction of the wire? Also, if we are given tension as well as the resistive forces (in the same direction e.g. resistive forces might include air resistence etc), is resistive forces included in tension? Many thanks

Tension is the force within the wire which opposes the weight acting in the opposite direction (usually mg but be careful as the equation changes if an angle is considered).

There may be other forces acting in the same direction as the tension in a particular question, but they would not (necessarily) be tensions themselves.

If you have two particles O---------------O joined by a string there such that it is taut, then there is tension acting to the right for the left particle, and there is an equivalent tension force acting to the left for the right particle. Both tension directions are along the string.
You cannot have any other forces 'inside' tension since tension is itself a force. A force inside a force doesn't make much sense.
