1. What is Linear Speed?

Linear speed is the rate at which an object moves along a circular path. It represents the distance traveled per unit time along the circumference of a circle and is calculated from angular velocity and radius.

2. How Does the Calculator Work?

The calculator uses the linear speed formula:

Where:

• \( V \) — Linear speed (m/s)
• \( \omega \) — Angular velocity (rad/s)
• \( r \) — Radius (m)

Explanation: The formula calculates the tangential speed of an object moving in a circular path by multiplying its angular velocity by the radius of the circular path.

3. Importance of Linear Speed Calculation

Details: Linear speed calculation is essential in various fields including physics, engineering, and mechanics. It helps determine the actual speed of objects in rotational motion, such as wheels, gears, and rotating machinery.

4. Using the Calculator

Tips: Enter angular velocity in radians per second (rad/s) and radius in meters (m). Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between linear speed and angular velocity?
A: Linear speed measures how fast an object is moving along a path (m/s), while angular velocity measures how fast it's rotating (rad/s).

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 angular velocity.

Q3: What if I have the frequency instead of angular velocity?
A: Angular velocity can be calculated from frequency using ω = 2πf, where f is frequency in Hz.

Q4: Does linear speed depend on the mass of the object?
A: No, linear speed depends only on angular velocity and radius, not on the mass of the object.

Q5: How is linear speed related to centripetal acceleration?
A: Centripetal acceleration is given by a = v²/r, where v is the linear speed and r is the radius.
