Consider the mechanism shown below, where link AB is rotating in the counter clockwise sense with a constant angular speed of ω AB. In summary, you should never assume that a zero value for angular ...

After leaving your hand, there is no torque so the angular momentum is constant. However, the angular velocity is not constant. Take a look at it in slow motion: Notice how the white side of the ...

Really. If you are moving in a straight line, you could think of this as a non-constant angular velocity. Also, you can think of the moment of inertia of the person as changing since the person is ...

and with the rotor rotating relative to that frame at a constant rate of ω 2. The goal of the problem is to calculate the angular acceleration of the rotor. The analysis for this is provided below.

The total orbital energy remains constant, so if the spacecraft ... or the direction of its Saturn-relative velocity modify Cassini's angular momentum, which results in a change in orbital ...
