On the whole we have weak forces.
However, the weak force, which governs beta decay and the corresponding nuclear transitions, "does" depend on the chirality of the interaction, and in this case pseudovectors and vectors "are" added.
Top quarks are so heavy that they decay through the weak force before they can form bound states.
But the consequent dispersion of their weak forces only exposed them to greater peril.
If it loses enough momentum through an inelastic collision, then it sticks onto the surface, forming a precursor state bonded to the surface by weak forces, similar to physisorption.
During the quark epoch, the electroweak force split into the electromagnetic and weak force.
This idea later found application in the quantum field theory of the weak force, and its unification with electromagnetism in the electroweak theory.
The sensitivity of the instrument comes from the weak spring constant of the fiber, so a very weak force causes a large rotation of the bar.
