The rotational analogue of this law equates the torque to the product of the moment of inertia and the angular acceleration.
In special relativity, this equation is modified by multiplying by gamma or gamma cubed, depending on whether two vectors are perpendicular or parallel. Adding a term including the change in mass with respect to time, or the thrust, to this law produces the rocket equation. A (*) free body diagram can be used to examine all the components involved in this law. The rotational analogue of this law equates the torque to the product of the moment of inertia and the angular acceleration. Its original form equates the time derivative of momentum to force, but one side is most often given in terms of acceleration. For 10 points, name this law of motion which states F equals m times a.
