6.3 Rotational Motion - Physics | OpenStax
https://openstax.org/books/physics/pages/6-3-rotational-motion
WebThe kinematics of rotational motion describes the relationships between the angle of rotation, angular velocity, angular acceleration, and time. It only describes motion—it does not include any forces or masses that may affect rotation (these are part of dynamics).

Angular velocity - Wikipedia
https://en.wikipedia.org/wiki/Angular_velocity
WebWith orbital radius 42,000 km from the Earth's center, the satellite's tangential speed through space is thus v = 42,000 km × 0.26/h ≈ 11,000 km/h. The angular velocity is positive since the satellite travels prograde with the Earth's rotation …

WebDec 30, 2020 · Unlike in linear motion, in rotational motion there is always acceleration, even if the rotational velocity \(\omega\) is constant. This acceleration originates in the fact that the direction of the (linear) velocity always changes as points revolve around the center, even if its magnitude, the net linear speed, is constant.
