1. | Displacement $\left( {\overrightarrow s } \right)$ | Angular displacement $\left( {\overrightarrow \theta } \right)$ |
2. | Velocity: $\overrightarrow v = \frac{{d\overrightarrow s }}{{dt}}$ | Angular velcoity: $\overrightarrow \omega = \frac{{d\overrightarrow \theta }}{{dt}}$ |
3. | Acceleration: $\overrightarrow a = \frac{{d\overrightarrow v }}{{dt}}$ | Angular acceleration: $\overrightarrow \alpha = \frac{{d\overrightarrow \omega }}{{dt}}$ |
4. | Mass: $M$ | Moment of inertia: $I$ |
5. | Force: $\overrightarrow F = M\overrightarrow a $ | Torque: $\overrightarrow \tau = I\overrightarrow \alpha $ |
6. | Work: $dW = \overrightarrow F .\;d\overrightarrow s $ | Work: $dW = \overrightarrow \tau .\;d\overrightarrow \theta $ |
7. | Kinetic energy of a translational motion, $${K_T} = \frac{1}{2}M{v^2}$$ | Kinetic energy of a rotational motion, $${K_R} = \frac{1}{2}I{\omega ^2}$$ |
