Linear and Angular Speed Calculator
🪐 Gravity & circular motion. Use the Linear and angular speed formula to find speed, angular velocity ω, radius: pick the value you want, type the others, and the answer updates as you go.
Speed3 m/s
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Speed | m/s |
| Angular velocity ω | rad/s |
| Radius | m |
Worked example
Find the speed when Angular velocity ω = 6 rad/s, Radius = 0.5 m.
Using v = ω r: Speed = 3 m/s.
Frequently asked questions
What is the formula for Linear and angular speed?
v = ω r.
What do the letters stand for, and what units are used?
Speed in m/s, Angular velocity ω in rad/s, Radius in m.
How do you calculate speed?
Put the values into v = ω r. For example, with Angular velocity ω = 6 rad/s, Radius = 0.5 m, speed = 3 m/s.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (speed, angular velocity ω, radius) and fill in the others: it rearranges the formula for you.
