Angular Velocity Formula:
From: | To: |
Angular velocity (ω) is a measure of the rate of rotation, describing how fast an object rotates or revolves relative to another point. It is measured in radians per second (rad/s) and represents the angular displacement per unit time.
The calculator uses the angular velocity formula:
Where:
Explanation: This formula converts linear velocity to angular velocity by dividing the linear speed by the radius of rotation.
Details: Angular velocity is crucial in various fields including mechanical engineering, robotics, physics, and astronomy. It helps in analyzing rotational motion, designing rotating machinery, and understanding celestial mechanics.
Tips: Enter linear velocity in meters per second (m/s) and radius in meters (m). Both values must be positive numbers greater than zero.
Q1: What is the difference between linear and angular velocity?
A: Linear velocity measures straight-line speed (m/s), while angular velocity measures rotational speed (rad/s). They are related through the radius of rotation.
Q2: What are typical angular velocity values?
A: Values vary widely - from very slow rotations (e.g., 0.00007 rad/s for Earth's rotation) to extremely fast rotations (e.g., 1000+ rad/s for high-speed motors).
Q3: Can this formula be used for any rotational motion?
A: Yes, this formula applies to any object moving in a circular path with constant radius, assuming the linear velocity is tangential to the circle.
Q4: What if the motion is not circular?
A: For non-circular paths, the concept of instantaneous angular velocity can still be applied using the instantaneous radius of curvature.
Q5: How does angular velocity relate to frequency and period?
A: Angular velocity relates to frequency (f) as ω = 2πf and to period (T) as ω = 2π/T.
