Question

What is angular acceleration​

Answer 1

Hey mate gm...

here is the answer of ur question ..

Angular acceleration, also called rotational acceleration, is a quantitative expression of the change in angular velocity that a spinning object undergoes per unit time. It is a vector quantity, consisting of a magnitude component and either of two defined directions or senses.

Answer 2

Angular acceleration is the time rate of change of angular velocity. In three dimensions, it is a pseudovector. In SI units, it is measured in radiansper second squared (rad/s2), and is usually denoted by the Greek letter alpha (α).[1]

Mathematical definitionEdit

The angular acceleration vector is defined as:

{\displaystyle {\boldsymbol {\alpha }}={\frac {d{\boldsymbol {\omega }}}{dt}}},

where {\displaystyle {\boldsymbol {\omega }}} (omega) is the angular velocity vector.
