A zero vector has physical significance in physics, as the operations on the zero vector gives us a vector.For any vector A , assume thatA + 0 = A A − 0 = AA × 0 = 0Again, for any real number λ we have:λ0=0The significance of a zero vector can be better understood through the following examples:The displacement vector of a stationary body for a time interval is a zero vector. Similarly, the velocity vector of the stationary body is a zero vector. When a ball, thrown upward from the ground, falls to the ground, the displacement vector is a zero vector, which defines the displacement of the ball.
