Frank Schneider Statics. not statistics. Statics is the study of material stress and forces that dont cause acceleration(aka net force is zero). But yes, statistics has no vectors.
As a science student, vectors for me were just on board or notebook, but never visualised as this much extent... Thank you for opening a new dimension of thinking
Vector is the sum of : The real distance travelled in space by an object in a straight line which can be expressed By an x coordinate or y coordinate of the destination point, or the sum of those two, in which the starting point is the origin of the cartesian plane which is assumed to be (0,0). The total distance travelled by that object cannot have intrinsic values because x coordinate cannot explicitly add y coordinate because their values might be different from each other. So, vector or denoted as "v" can be expressed by v=[x] [y] in two-dimensional array. Or, v=xi + yj ; Note that x value cannot be added explicitly to y value. The equation is just some sort of expression, not intrinsic addition. As for the vector magnitude, it is actually the displacement of the distance travelled by that object from origin to endpoint of the destination, in which can also be expressed as the hypotenuse of a right angle triangle with the x coordinate as the adjacent side, while y coordinate as the opposite side. As for unit vector, ^v = v/|v| This means, to get x and y coordinate of the unit vector with its magnitude as 1. I.e, the hypotenuse of coordinate x and y has the intrinsic value of 1.
It took me 45 min to figure out why the vectors and how the vectors could possibly be the same considering clearly going In opposite directions. Can you tell me if my epiphany was correct;? It was this: The only way these can possibly be the same vectors is from the perspective of a being that itself is moving from the origin: if a person/perspective moves up to right 3 or left 2 down 3, from their perspective they still moved the same amount relative to the “center” origin! Did I do a good epiphany!???
3:34 “Even if you have forces acting in the same direction with the same magnitude depending on how they’re oriented you might see waves or whirls when force a vector is combined with another vector we have the physical quantity called stress which is an example of a second order tensor.”
This brings back to me a question that I've had for quite a while. Once I was trying to code a plane which each pixel would have a vector value and these would spread out at some percent in "time" so that it would be able to simulate waves. However, before I started too do any coding, I came across a really confusing scenario. If you have two waves coming in opposite directions which consequently annihilate each other towards the middle of the plane, I would expect them to continue after colliding, but it wouldn't be the case. All the information each pixel would have as data is the direction and momentum, but as these two opposing waves collide they would essentially wipe clean all data rendering impossible for the waves to go past each other as it happens in the real world. All I can think of to overcome this issue is creating a new instance of a plane for each new circular wave generated but this wouldn't be neither efficient nor practical.
@@horsecurse dang I did not even remember I had asked this. Yeah, you're in the right direction, but I think here it'd be more convenient to track the properties of discrete points in the plane. What I was describing was basically a tensor field. A tensor can hold on information about the "elasticity" and momentum of the field. Thank you for reminding me of this though. I never coded a tensor field, and I'm now curious if I can make it through with what I now know.
I wish we had this explanation available when I was a kid. Our teachers didn't have the tools to convey the information. And by tools I means the intelligence or the creativity required to convey it.

Considering force is a vector one might thing pressure is a vector too. But the direction of the force, caused by a pressure (difference) is determined by the orientation of the area the force is acting on. The force is obviously always perpendicular to the area. Therefore F=p n A with force vector F, area A (skalar) and vector n (unit vector normal to the area)
Actually, pressure at a point on plane surface is defined as the magnitude of normal component of force acting per unit area around the point. It doesn't follow laws of vector addition i.e., parallelogram law of vector addition or triangle law of vector addition or polygon law of vector addition.In physics, when we talk about pressure , we mean magnitude of fore acting per unit area. It doesn't require extra piece of information to be known i.e., direction. Since a physical quantity pressure is expressed in terms of magnitude only, we can conclude that it's a scalar quantity.

Because pressure does not have a specific direction.
because pressure p is defined as Force per Area -> p=F/A

Considering force is a vector one might thing pressure is a vector too. But the direction of the force, caused by a pressure (difference) is determined by the orientation of the area the force is acting on. The force is obviously always perpendicular to the area.
