Webparticles. The system rotates about the x axis with an angular speed of 2.10 rad/s. • a) Find the moment of inertia about the x axis. • b) Find the total rotational kinetic energy … WebAngular acceleration α is defined as the rate of change of angular velocity. In equation form, angular acceleration is expressed as follows: where Δ ω is the change in angular velocity and Δ t is the change in time. The units of angular acceleration are (rad/s)/s, or rad/s 2. If ω increases, then α is positive. enter the odyssey galaxy campaign
