can anyone tell me what it is.i heard that this is important if you are making a drone

Imagine standing on the edge of a rotating disk. You’re moving decently fast right? Now imagine that instead, you are now closer to the middle of that disk. You’re much slower now. What changed? What remains constant?
This is where angular velocity and *linear* velocity make a difference. In both cases, the rate of angle change, or how many rotations/revolutions per unit time remains the same. You make a circle in the same amount of time no matter where on that disk you stand. But in order to accommodate that, the “you” standing on the edge of the disk will need to cover more ground (i.e. the entire circumference) compared to the “you” standing near the centre in the same amount of time. Hence, you will need a larger linear velocity (a greater speed) to finish that revolution if you are going around the disk’s edge.
It is generally more beneficial to use angular velocity to determine how fast a drone can rotate in any of the 3 axes, rather than its linear velocity at any point.
