Write a short note on vector product between two vectors.

Explanation

Torque `vectau=vecrxxvecF`. Where `vecF` is force and `vecr` is position vector of a particle.
(i) Angular momentum `vecL=vecrxxvecp` where `vecp` is the linear momentum.
(iii) Linear velocity `vecv=vecomegaxxvecr` where `vecomega` is angular velocity.
