The tendency of an object to keep rotating; the rotational version of linear momentum. A vector quantity with magnitude and direction.

The resistance of an object to rotational motion (kg·m²).

The rate at which an object is rotating or revolving, measured in radians per second (rad/s).

The change in angular momentum caused by a torque acting over a time interval.

A rotational force (N·m).

The angular impulse equals the change in angular momentum: $\Delta L = \int_{t_1}^{t_2} \tau , dt$

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.

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.
