Calculate linear speed instantly with our easy online Linear Speed Calculator. Enter radius and angular speed to get fast, accurate results.
Linear speed can feel tricky at first. But it’s actually simple. You only need a radius and an angular speed. That’s it. Our linear speed calculator uses these values to give you the exact speed in a flash. You’ll get clean results with no stress.
If you want a tool that makes physics feel easy, you’re in the right place.
Linear speed tells you how fast an object moves along a straight path. Think of a kid on a bike moving around a park. Even if the bike goes in circles, you can still measure how fast it moves forward. That forward speed is the linear speed.
It’s simple. It’s the “real world” speed of an object that spins or rotates.
The formula is short and sweet:
v = r × w
If you know the radius and the angular speed, you can find linear speed in one quick step.
Our tool uses the same physics formula. But it also converts units for you. So you don’t need to worry about meters, feet, radians, or rotations. You just enter numbers and choose units.
The calculator does this:
You’ll get a clean, accurate value right away. No extra math. No long steps.
That’s it. You’ll see the linear speed at once.
Let’s try one example.
Say the radius is 50 meters.
The angular speed is 100 rad/s.
Use the formula:
v = r × w
v = 50 × 100
v = 5000 m/s
The object moves at 5000 meters per second. That’s fast!
You see linear speed in daily life. A fan blade spins. A wheel turns. A ride at a fair rotates. All these objects have angular speed. But we also want to know how fast the outer edge moves. That’s where linear speed helps. It tells the real pace of motion in simple terms.
Linear speed is easy to understand when you break it down. Our calculator makes the job even easier. You enter a radius and an angular speed. You get the exact speed in clear units. Fast, simple, and accurate. If you work with physics, machines, or motion, this tool saves time and keeps things stress-free.
Linear speed is how fast an object moves along a straight line in space.
No. Speed ignores direction. Velocity includes direction.
Yes. It’s common in rotation, motion, and basic mechanics.
You can use meters, feet, miles, radians per second, degrees per second, rpm, and more.
Yes. Wheels, gears, fans, motors anything that rotates.
