At t 2, the angular velocity is zero, with a non-zero (positive) angular acceleration. At that time, the direction of rotation for BC is changing from CW to CCW. In summary, you should never assume ...

With an angular velocity of 0.02328 radians per second, I get a ground speed of 116 m/s (260 mph). This means the plane is moving with the same velocity (but in the opposite direction).

Instead of velocity we say, “angular velocity,” which measures how fast an object rotates. Finally, instead of momentum, we say “angular momentum.” Even though the terms are a little ...

Now for angular momentum. The angular momentum is a quantity that we can calculate for rotating object. It's the product of the angular velocity (how fast it spins—represented with the symbol ω ...

Stretching the limbs out will increase the moment of inertia, therefore decreasing the angular velocity — which is essential for a neat and flawless dive into the water. Phase 2.
