2.4. Angular acceleration

Lecture



In case of uneven movement 2.4.  Angular acceleration does not remain constant. The value characterizing the rate of change of the angular velocity is called the angular acceleration and is equal to:

2.4.  Angular acceleration (2.5)

In the case of rotation of the body around
fixed axis change vector 2.4.  Angular acceleration due only to a change in its numerical value. With this vector 2.4.  Angular acceleration angular acceleration is directed along the axis of rotation in the same direction as 2.4.  Angular acceleration with accelerated rotation 2.4.  Angular acceleration and in slow motion 2.4.  Angular acceleration in the opposite direction. (fig. 2.3 a), b))
