The 'rotational oomph' of an object; the tendency of a rotating object to keep rotating.

A measure of how hard it is to change an object's rotation.

How fast an object is spinning.

Rotational force that causes things to rotate.

The product of torque and time; what changes an object's angular momentum.

The sum of all torques acting on an object.

The rate of change of angular velocity.

The object experiences angular acceleration.

Their moment of inertia decreases, and their angular velocity increases (angular momentum remains constant).

The object's angular momentum changes.

The object's angular momentum changes.

The angular momentum increases (assuming other variables remain constant).

The angular momentum of the system remains constant (conservation of angular momentum).

Use the formula: $L = I\omega$, where L is angular momentum, I is moment of inertia, and ω is angular velocity.

Use the cross product: $\vec{L} = \vec{r} \times \vec{p}$, where $\vec{L}$ is angular momentum, $\vec{r}$ is the position vector, and $\vec{p}$ is linear momentum.

Calculate the area under a torque vs. time graph.

Subtract the initial angular momentum from the final angular momentum: $\Delta L = L - L_0$.

Find the slope of the angular momentum vs. time graph.
