û = v/|v| = (1/√6)i + (1/√6)j + (2/√6)k That's it. û is the unit vector in the direction of v. Is the dot product of two vectors in the same direction positive or negative? The dot product of two vectors in the same direction is always positive. That's becau...
Given are two vectors a=[1, 8, 4] b=[3, 5, 9]. Find the angle between them Force A acts 2 N west and 3 N south. Force B acts 5 N west and 2 N north. What is the overall magnitude and direction of the resultant vector? Ass...

Each of the examples above involves magnitude and direction.Remember: A vector is not the same as a scalar. (see Part 1 on MiLearn.com) . Scalars have magnitude only. For example, a speed of 35 km/h is a scalar quantity, since no direction is given. Other examples of scalar ...
Magnitudeis "how large' something is . In the diagrams 1 and 2, you can see vectors that have magnitudes of 4 and of 5. Diagram 1 Diagram 2 Trait #2) Direction The meaning of direction is pretty self explanatory. The vector must start somewhere and move in a path towards a different...
