From the free-body diagram, we found the positions of the center of mass in the initial moment. We merged all relations and found the relation for the angular velocity, and after calculation, we got that the velocity of the angular velocity of bars at the final moment was 3 g sin θ / L sqrt{3gsin{theta}/L} 3 g sin θ / L .

Angular Displacement Angular displacement is defined as the change from the final position to the initial position (Δθ = θ f – θ i).Angular displacement represents the angle formed between the final position and the initial position of a rotating line. As with linear displacement, angular displacement has a direction associated with it.

Early in Lesson 1 it was mentioned that there are a variety of means of describing the motion of objects. One such means of describing the motion of objects is through the use of graphs - position versus time and velocity vs. time graphs. In this part of Lesson 5, the motion of a free-falling motion will be represented using these two basic types of graphs.
