1. What is Angular Velocity?

Definition: Angular velocity (ω) measures how fast an object rotates or revolves relative to another point, describing the rate of change of angular displacement.

Purpose: It's crucial in physics and engineering for analyzing rotational motion in objects like wheels, gears, planets, and more.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \omega \) — Angular velocity (radians/second)
• \( \Delta \theta \) — Change in angular position (radians)
• \( \Delta t \) — Change in time (seconds)

Explanation: The change in angle is divided by the time taken for that change to occur.

3. Importance of Angular Velocity

Details: Understanding angular velocity helps in designing mechanical systems, analyzing planetary motion, and solving problems in rotational dynamics.

4. Using the Calculator

Tips: Enter the angle change in radians and the time change in seconds. Time must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert from degrees to radians?
A: Multiply degrees by π/180 (≈ 0.01745). Our calculator requires radians.

Q2: What's the difference between angular velocity and linear velocity?
A: Angular velocity measures rotational speed, while linear velocity measures straight-line speed (v = rω, where r is radius).

Q3: Can angular velocity be negative?
A: Yes, negative values indicate rotation in the opposite direction (typically clockwise).

Q4: How is angular velocity related to frequency?
A: ω = 2πf, where f is frequency in Hz (revolutions per second).

Q5: What are typical units for angular velocity?
A: Radians per second (rad/s) is standard, but degrees per second and revolutions per minute (RPM) are also used.
