1. What is Linear Speed?

Linear speed is the distance traveled per unit of time along a straight path. It represents how fast an object is moving in a straight line, typically measured in miles per hour (mph) or meters per second (m/s).

2. How Does the Calculator Work?

The calculator uses the linear speed formula:

Where:

• \( V \) — Linear speed (mph)
• \( \omega \) — Angular velocity (radians per second)
• \( r \) — Radius (meters)
• 2.23694 — Conversion factor from m/s to mph

Explanation: The formula converts rotational motion to linear motion and then converts the result from meters per second to miles per hour.

3. Importance of Linear Speed Calculation

Details: Calculating linear speed is essential in various applications including automotive engineering, sports science, mechanical design, and physics education. It helps determine how fast a point on a rotating object is moving in a straight line.

4. Using the Calculator

Tips: Enter angular velocity in radians per second 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 linear speed?
A: Angular velocity measures how fast something rotates (radians per second), while linear speed measures how fast it moves along a straight path (mph or m/s).

Q2: Why is there a conversion factor of 2.23694?
A: This factor converts meters per second to miles per hour (1 m/s = 2.23694 mph).

Q3: Can I use this calculator for any rotating object?
A: Yes, as long as you know the angular velocity and the radius from the center of rotation to the point of interest.

Q4: What if my angular velocity is in RPM instead of rad/s?
A: You'll need to convert RPM to rad/s first (1 RPM = π/30 rad/s ≈ 0.10472 rad/s).

Q5: How accurate is this calculation?
A: The calculation is mathematically precise based on the inputs provided. Accuracy depends on the precision of your measurements.
