Angular Displacement (θ):
* Definition: The change in angular position of an object. It's the angle through which an object rotates.
* Units: Radians (rad) or degrees (°).
* Example: If a wheel rotates by 90°, its angular displacement is 90°.
Angular Velocity (ω):
* Definition: The rate of change of angular displacement. It tells us how fast an object is rotating.
* Units: Radians per second (rad/s) or degrees per second (°/s).
* Example: If a wheel rotates 360° in 1 second, its angular velocity is 360°/s or 2π rad/s.
Analogy:
Think of it like this:
* Angular displacement is like the total distance traveled by a car.
* Angular velocity is like the speed of the car.
Key Difference:
Angular displacement is a position measurement, while angular velocity is a rate of change measurement.
