21 Μαΐ 2023 · In fact, most problems can limit torque (and angular acceleration) to just "clockwise" and "counterclockwise" – the direction of the torque vector can be left until the end. One must either know or be able to calculate the rotational inertia of the object on which the torques acts.
Equation 10.25 is Newton’s second law for rotation and tells us how to relate torque, moment of inertia, and rotational kinematics. This is called the equation for rotational dynamics . With this equation, we can solve a whole class of problems involving force and rotation.

Figure \ (\PageIndex {3}\): Some rotational inertias. The general relationship among torque, moment of inertia, and angular acceleration is \ [net \, \tau = I \alpha\] or \ [\alpha = \dfrac {net \, \tau} {I},\] where net \ (\tau\) is the total torque from all forces relative to a chosen axis.
