1. What is Tangential Velocity?

Tangential velocity is the linear speed of an object moving along a circular path. It represents how fast the object is moving tangent to the circular path at any given point.

2. How Does the Calculator Work?

The calculator uses the tangential velocity formula:

Where:

• \( v \) — Tangential velocity (m/s)
• \( rpm \) — Rotations per minute (rev/min)
• \( r \) — Radius (m)
• \( \pi \) — Mathematical constant (approximately 3.14159)

Explanation: The formula converts rotational speed (rpm) to linear speed by accounting for the circumference of the circular path and converting minutes to seconds.

3. Importance of Tangential Velocity Calculation

Details: Calculating tangential velocity is essential in mechanical engineering, physics, and various industrial applications where rotational motion needs to be converted to linear motion analysis.

4. Using the Calculator

Tips: Enter RPM in revolutions per minute and radius in meters. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between angular velocity and tangential velocity?
A: Angular velocity measures how fast an object rotates (radians per second), while tangential velocity measures the linear speed along the circular path (meters per second).

Q2: Can this formula be used for any circular motion?
A: Yes, this formula applies to any object moving in a circular path with constant rotational speed.

Q3: Why divide by 60 in the formula?
A: The division by 60 converts minutes to seconds, as RPM is in revolutions per minute while velocity is typically measured in meters per second.

Q4: What if I have diameter instead of radius?
A: Simply divide the diameter by 2 to get the radius before using the calculator.

Q5: Does this work for variable RPM?
A: This formula calculates instantaneous tangential velocity for a given RPM value. For variable RPM, the calculation would need to be done for each specific RPM value.
