Multiplying a vector by a negative scalar changes its magnitude and direction oppositely.
When a vector is multiplied by a scalar, if the scalar is negative, it changes the vector's magnitude and direction oppositely. For example, multiplying a vector by -2 results in the magnitude doubling while changing the direction.
Multiplying a vector by a scalar involves multiplying each component of the vector individually by that quantity. This process also affects the magnitude of the vector accordingly.
Key takeaway: Multiplying a vector by a negative scalar alters both magnitude and direction oppositely.
