Whether you're dealing with RPM values or angular velocity, this tool ensures quick and accurate results.

This calculator is designed to provide a user-friendly experience for students, professionals, and enthusiasts. It supports multiple calculation methods, making it versatile and highly effective.

What is Linear Velocity?

Linear velocity refers to the rate at which an object travels along a straight path. It measures how far an object moves in a specific direction over a given time. The formula for linear velocity is:

Linear Velocity (v) = Angular Velocity (ω) × Radius (r)

Linear velocity is commonly expressed in meters per second (m/s) or kilometers per hour (km/h).

How to Use the Linear Velocity Calculator

Using our Linear Velocity Calculator is straightforward:

  1. Select the calculation method: RPM or Angular Velocity.
  2. Enter the required values:
    - For RPM, input the revolutions per minute.
    - For Angular Velocity, input the value in radians per second (rad/s).
  3. Specify the radius of the object in meters.
  4. Click "Calculate" to get the results instantly.

The tool provides detailed outputs, including angular velocity, linear velocity, circumference, time per revolution, and more.

Formula and Example Calculation

Formula:

Linear Velocity (v) = ω × r

Where:

ω = Angular Velocity (rad/s)

r = Radius (m)

Example:

If an object has an angular velocity of 10 rad/s and a radius of 2 meters:

v = 10 × 2 = 20 m/s

The object's linear velocity is 20 meters per second.

Visualization and Tables

Our calculator not only provides numerical results but also visualizes the relationship between radius and linear velocity. The graph below demonstrates how linear velocity changes with varying radii.

Table: Sample Calculations

Chart: Linear Velocity vs Radius

The chart shows that as the radius increases, the linear velocity also rises proportionally, assuming a constant angular velocity.

FAQs

What is linear velocity?

Linear velocity is the distance covered by an object per unit time along a straight path.

How do you calculate linear velocity from RPM?

To calculate linear velocity from RPM:

Convert RPM to angular velocity (ω): ω = (RPM × 2π) / 60.

Use the formula v = ω × r.

Can I calculate linear velocity in km/h?

Yes, our calculator provides linear velocity in both meters per second (m/s) and kilometers per hour (km/h).

What is the relationship between radius and linear velocity?

Linear velocity is directly proportional to the radius. As the radius increases, the linear velocity also increases.

Final Verdict

The Linear Velocity Calculator is a versatile and user-friendly tool designed to make complex calculations simple. Whether you’re studying physics, designing mechanical systems, or simply curious about motion, this calculator is your go-to resource.
