\vec{F}The LaTeX command \vec{F} is used to denote a vector quantity, typically in physics and mathematics. The vector accent is placed over the letter 'F' to indicate that it is a vector, which has both magnitude and direction.
Newton's second law of motion, where \vec{F} is the force vector, m is mass, and \vec{a} is the acceleration vector.
\vec{F} = m \vec{a}Lorentz force equation, where \vec{F} is the force on a charge q moving with velocity \vec{v} in electric field \vec{E} and magnetic field \vec{B}.
\vec{F} = q(\vec{E} + \vec{v} \times \vec{B})Hooke's law for springs, where \vec{F} is the restoring force vector, k is the spring constant, and \vec{x} is the displacement vector.
\vec{F} = -k \vec{x}
