The speed which is known as the angular speed is the measure of how fast the central angle of a rotating body changes with respect to time. Angular speed formula is the relationship between angular speed and the speed which is linear along with a few angular speed problems.
The term speed that is used in various contexts earlier. For instance, we should know how fast we are driving our car or how fast we pitch a ball. Similarly, speed is basically referring to how slow or we can say how fast the object is moving. Thus the angular speed is how quickly an object rotates. In other words, it is described as the change that is in the angle of the object per unit of time.
Therefore if we want to calculate the speed of the rotational motion then we will be requiring the angular speed of it. The angular speed formula calculates the distance the body covers in terms of revolutions or rotations to the time taken.
Furthermore, the radian is quite an important thing here. To calculate the angular speed, the angle we measure is in radians. Radians are said to be a way of measuring angles where we define the right angle as pi/2 radians. Therefore one full revolution will contain around 6.28 radians.
We see that the angular speed is the rate at which an object changes its angles which we measure in radians in a given time. The angular speed has a magnitude that is a value only.

Where:
- Symbol ω refers to the angular speed in radians/sec.
- The symbol θ is the angle in radians (2π radians = 360 degrees).
- t refers to the time, sec.
It is important to note that angular speed and as well as the angular velocity make use of the same formula. However, the difference between the two is that angular speed is a scalar quantity whereas the angular velocity is a vector quantity.
