1. Conservation of angular momentum and its counterpart for linear momentum

Hmmm, so how correct is summarizing the situation as follows? CW motors experience a drag force from the air which will result in a torque which will result in a rotation CCW around the vertical axis(origin at center of gravity of the quadcopter). So as rpm of CW motors increase relative to...
2. Conservation of angular momentum and its counterpart for linear momentum

But, what the guys rotating themselves with a rotating bicycle wheel are demonstrating then? Isn't it conservation of angular momentum? Are they isolated? See this link for what I'm talking about.
3. Conservation of angular momentum and its counterpart for linear momentum

Then the thing which aparts my quadcopter example from the car example is the fact that quad motors(by propellers) are better in being able to influence their systems (quadcopter + air) compared to car motors(by wheels) and their systems (car + earth). And that is probably because car motors...
4. Conservation of angular momentum and its counterpart for linear momentum

Interesting... So, I should consider car + Earth surface as my system, then a component in the system (car) may not be preserved its linear momentum, but for the whole system, it is preserved since Earth surface is moving twords the opposite way with lots of mass but very little speed. Something...
5. Conservation of angular momentum and its counterpart for linear momentum

For a car going in forward direction, the wheels are generating an angular momentum(or torque) pointed towards the left. So, for balancing, the body of the car wants to generate a torque towards right, which could be obtained if the car were rotating so that it pitches its nose up. That's why...
6. Conservation of angular momentum and its counterpart for linear momentum

Hi, I have just joined the forum. Thank you all for being a part of such places so that people like me can get answers to the questions on their minds! --------------------------- I have been trying to understand how a quadcopter yaws. Referring to the figure below which is bird's eye view of...
