Velocity & Force on a Moving Charge in Magnetic Field

Are there components of the velocity that cannot be determined by measuring the force if one looks at the formula F = q*B*v?

For non-relativistic cases, the vector form of that equation provides all info concerning the force exerted on a moving charge by a magnetic field:
$$:\qquad \underline{F} \ = \ q\underline{v}\times \underline{B}$$
