Answer to Question #281262 in Physics for Reinn

Question

Identify and explain the dynamics in rotational motion. Compare the dynamics in rotational

motion to the equivalent translational motion.

Answer 1

Kinematics of rotational motion explains the motion of particles or objects that perform motion in circular trajectories.

$$\alpha=\frac{\omega_f^2-\omega_i^2}{2\phi}↔ a=\frac{v_f^2-v_i^2}{2d}.\\\space\\ \Delta\omega=\alpha t↔ \Delta v=at.\\\space\\ \phi=\frac 12 \alpha t^2↔ d=\frac12at^2.$$
