Answer:
it is true because ...
if m×v=0, then 1/2 m×v^2 is also zero

Answer:
Classically, the answer is “no.” Momentum (p = mu) and kinetic energy (KE = mu2∕2) are proportional to the mass m. If m = 0, then p = E = 0. ... That would mean E = pc and hence, that m = 0, i.e., it would be a massless particle.
