Being A Vector

"That is what you need to be. You need to be vectors because you need to have a direction."
-Dr Christopher Monterola pertaining to his students during his lecture about vectors in Physics 101

In fact, Sir Chris is absolutely right with what he said. Everyone needs to be a vector. It is because the magnitude is not the only thing that matters when it comes to this life. That magnitude of life needs to have a direction. And take note: it should be the right direction.

To recall, scalars pertain to the magnitude only. On the other hand, vectors pertain to both magnitude and direction. Those definitions set the walls up in between distance and displacement, speed and velocity, among others.

As Sir Chris had stated in an example, consider two points in a plane. One can travel from one point to another in various ways. One can go side by side into long routes but still finds the end at the same point. That then makes up the distance, which then varies on the way how one got from one point to another. On the other hand, the displacement pertains not only to shortest distance to the other point but also to where exactly that point with respect to where the observer is.

The ones mentioned above are the ones discussed in physics. But as always said in this site, everything in physics connects to the everyday life.

Everyone does a thing in various ways. Take an old man for example. He might do a job in his own conventional way. However, there also is a younger man who prefers the modern way. In the end, they still will arrive on the same thing, which is finishing the job depending on how much effort they exerted.

Furthermore, those efforts of both men explains that it is still not enough to pour much effort to end up with a good job. One also needs to see where he is heading onto.

And after that lecture, I really see that I already had entered another chapter in my life - and it is entitled "college physics."
