As the designation 'first' and 'second' (in this case) is purely objective (assigned by the viewer) there is no special terminology applied as both forces are exactly the same force and are known by exactly the same terms:
resistance force
reacting force
The "reaction" force.

reaction
A force is the total force felt by an object
an object's mass
The unbalanced force acting on an object equals the object's mass times it acceleration. The equation to find force is as follows.Force=mass*accelerationf=mv
Weight
