I just can’t wrap my head around why the direction of the angular displacement and the angular velocity are perpendicular to the plane. How does this make sense? Why isn’t the direction in the direction of the movement?

I don't know if you can think of it this way, but think of it as you're unscrewing a screw or tightening a nut. Lefty loosey, righty tighty. Assuming that you're looking straight down at the screw or nut, when you create an angular velocity to left the screw or nut comes out towards you (perpendicular to the plane which the screw sits). Likewise, creating an angular velocity to the right tightens the screw (goes in the negative y-direction). Hope that helps!

Historical reasons, but it does have some advantages and simplification in equations. Mathematicians wanted to extend imaginary numbers into another system b/c they described rotations well. Unfortunately this only works nicely in four dimensions. Then they realized that the ‘3-dimensional parts’ of products are what we now call cross products, and soon they were shown to have applications in physics such as electrodynamics, where some fields created things perpendicular to them EXACTLY like a cross product (I do math, not physics so I’m not aware of the details). Anyways, time went by and they found more things that behaved like this. Eventually, people stopped using quaternions and instead just used their 3-dimensional part, vectors, giving rise to cross and dot (the fourth dimensional, scalar or ‘number’ part) of two vectors. Both of these products became ubiquitous in math, the cross product being related to areas, in the end because you get the same formula either way and its simplier and easier to communicate when fewer ideas are used, moreover they are relatively easy to visualize. Such products also explain angular velocity well. What flipping physics said, the cross product describes rotation of an entire 3d space or rigid object - try thinking about it the other way around; dont curl you fingers to find the direction of omega, think about pointing in a direction and then curling your fingers around to rotate an object; it will just appear to natural to specify the rotation by using the axis of rotation basically. (Sorry for being rambly, I should have put that last sentance at the beginning)

Mr P, why is the direction recquired to be crossed in other words why is the direction like it is? Why isn't it in the direction of angle encompassing? (Think of the last sentence as if someone is swahing opeing the angle so that direction)

i see how counter clockwise and clockwise are observer dependent but is the direction of the torque also either Positive or negative dependent on which way the observer defines as positive or negative? what if i was upside-down looking at a disc. (or on the other side of the earth) our direction of torque would be the same but I would say it's positive while you might say it is negative?
@FlippingPhysics4 жыл бұрын
The x,y,z coordinate system defined is independent of the observer. Two different observers may get into fisticuffs over how to define that system, however, in the end, no matter who observes the coordinate system, it will be the same.

So, why doesn't the mint fly straight up into the air ,perpendicular to the plane, due to its angular velocity and what about the direction of angular acceleration?
@carultch3 жыл бұрын
Because the angular velocity is assigned to the axis of rotation in accordance with the right hand rule. It is bookkeeping to make this choice, not reality. It is an arbitrary choice which spatial direction we should assign to angular kinematics, and the choice that prevails is to assign it to the axis of rotation where it would point toward the observer who sees it rotating counter-clockwise.
@learningisecstatic93485 жыл бұрын
Dearest sir, I am struggling since my high-school days to understand why the direction of angular velocity and angular displacement is thus defined? One doubt is answered that why we should not associate clockwise or anticlockwise direction to it. But till I just don't understand why are they so defined as determined by right hand rule? Sir please answer.

Most threaded fasteners are designed with right-handed threads. If the rotating body were a nut spinning on a threaded rod, it would simultaneously translate in the direction we assign for angular kinematics. It is a convention. That is all. We could've picked any other direction, and the axis of rotation is the choice that prevailed, such that it faces toward the observer who sees it rotating counter clockwise. We have an intuition about this, because most fastener threads are standardized on right-handedness, unless there is a compelling reason to use a left-handed thread (like on your left bike pedal).

Sir, I have got a question......we have taught in our school that displacement vector is given by subtraction of position vector for that particle.....and further we use right hand thumb rule for vector product of two vector quantities, so why are we using right hand thumb rule rather than just doing subtration of those vector quantities ?🤔
