Angular Velocity
* Definition: Angular velocity (ω) is the rate of change of angular displacement. It's measured in radians per second (rad/s).
* Calculation:
* The second hand completes a full circle (2π radians) in 60 seconds.
* Therefore, ω = (2π radians) / (60 seconds) = π/30 rad/s
Angular Acceleration
* Definition: Angular acceleration (α) is the rate of change of angular velocity. It's measured in radians per second squared (rad/s²).
* Calculation:
* The second hand moves at a constant speed, meaning its angular velocity doesn't change.
* Therefore, the angular acceleration is zero (α = 0 rad/s²).
In Summary
* Angular velocity (ω): π/30 rad/s
* Angular acceleration (α): 0 rad/s²
