Therefore the magnitude of the vector 3i +4j, is 5 units. This statement can be mathematically written as: |3i+4j| = 5. (The vertical lines mean magnitude).

How do you find a vector given its magnitude?

For example, if we know the magnitude of a vector sqrt(2) and the angle is 45 degrees, then we use cos(45) = x/sqrt(2) which implies that x = 1; similarly, cos(45) = y/sqrt(2) which implies that y =1. So, our vector is (1, 1). One way is to multiply the unit vector (cos(theta),sin(theta)) by the magnitude.

Is Velocity a scalar?

We define a vector as an object with a length and a direction. However, there is one important exception to vectors having a direction: the zero vector, i.e., the unique vector having zero length. With no length, the zero vector is not pointing in any particular direction, so it has an undefined direction.
