Question

Express the unit vector a in mathematical form

Answer 1

To find a unit vector with the same direction as a given vector, we divide by the magnitude of the vector. For example, consider the vectorv = (1, 3) which has a magnitude of . If we divide each component of v by we will get theunit vector uv which is in the same direction as v: .

Answer 2

Answer:

Vector is a quantity that has both magnitude and direction but not position. Examples of such quantities are velocity and acceleration.
