Newton's Laws


The analogy between translational kinematics and rotational kinematics extends to the relationship between translational dynamics and rotational dynamics.

Once you are clear on this understanding, and you are comfortable with the definitions of the rotational quantities, most problem solving in rotational mechanics follows pathways you have already mastered.

While the net force on an object equals the rate of change of its momentum, the net torque represents the rate of change of angular momentum. A force produces an acceleration; a torque produces angular acceleration.
