NettetWhen the angular speed changes with time, we define instantaneous angular velocity as a = lim - A0 = - dB A,+O At dl (4 b) d de is a vector as it is an infinitesimal angular displacement. We can write d 0 =-dtdt. Since dt is a scalar, - do will he a vector, i. the instantaneous angular velocity wis a dt vector quantity. NettetIf we divide dω by dt, we get the instantaneous angular acceleration dα. If the angular acceleration is constant, we can say dα = α.
