In general, the Lorentz force is [ F = q(E + v x B) ].

No. The vectorial definition of Lorentz force is
F = q[E + (v x B)]
If a particle has no velocity, then the cross product of the velocity vector and the magnetic field vector is the null vector, but there will still be a Lorentz force if there is an electric field.
For a particle not to experience Lorentz force, it must either not be electrically charged and/or not be put in an electromagnetic field with a certain velocity.

The Lorentz force, in electromagnetism, is the effect of electric and magnetic forces which act on a point charge moving through electric and magnetic fields.
The Lorentz force can be found in scientific apparatus such as particle accelerators, mass spectrometers and magnetrons. More day-to-day equipment are electric motors, loudspeakers and electrical generators.

This is the Electromagnetic force.
(Technically, it's the Lorentz force, which is the force on a
charge due to an electromagnetic field, but either will do.)

If a charged particle moves in a magnetic field then Lorentz
magnetic force acting will be perpendicular to its movement and so
the particle will be taken along a curved path. Lorentz force will
be towards the centre of the curved path. Any force facing towards
the centre of the curved path is named as centre seeking or
centripetal force.
