What is angular speed in physics?
0:02
Angular speed is the rate at which an
0:04
object rotates or moves through an angle
0:07
with respect to time. Angular speed
0:09
describes how fast an object is rotating
0:14
It tells us how much angle is covered in
0:17
a given time. Angular speed is a scalar
0:20
quantity, meaning it has magnitude only
0:25
The SI unit of angular speed is radians
0:28
per second rad s. It is commonly used in
0:31
circular motion and rotational motion to
0:34
describe how quickly an object spins.
0:37
Imagine a ceiling fan rotating. The
0:39
faster it spins, the greater its angular
0:42
speed. Example: building, rotation of a
0:44
ceiling fan, spinning of a wheel, motion
0:47
of a merry-go-round, Earth rotating
0:50
about its axis, blades of a turbine
