Linear speed calculator helps you find how fast an object is moving in a straight line by calculating its linear speed, based on the angular velocity and radius of the rotation.
This is How Linear Speed Calculator Works:
Calculate the linear speed in one click by following the simple steps shown below:
What to Enter?
- First, select the parameters in which you want to calculate
- Next, enter the values of angular velocity and radius of the rotation
What will you Get?
- Linear speed values along with step-by-step calculations
What is Linear Speed?
“Linear speed refers to the rate at which an object moves along a straight path.”
It is typically measured in meters per second (m/s).
A car is moving on a highway and the speedometer shows the linear speed, indicating how fast the car is covering the distance. For example, the car’s speedometer indicates 60 miles per hour this represents its linear speed along the road.
Linear Speed Formula:
Here is the basic formula to calculate the linear speed:
v = ωr
- v – Linear Speed (m/s)
- w – Angular Velocity (rad/s)
- r – Radius of the circular path
How to Calculate Linear Speed?
We recommend you use the linear speed calculator to calculate the linear speed faster. But if you want to calculate it manually, then follow the example shown below:
Let's say you have a bicycle tire that is spinning at an angular speed of 10 (rad/s) and the radius of the tire is 0.3 meters. We want to find the linear speed (v) in meters per second.
Let’s use the linear speed formula:
v = ωr
Now, put the values into the equation:
v = 10 (rad/s) x 0.3 meters
v = 3 (m/s)
So, the linear speed of a point on the edge of the bicycle tire is 3 (m/s).
Linear Speed Common Examples:
Here is a table of some common examples through which you can easily get an idea about the linear speed of common objects:
|Object||Linear Speed (v)||Angular Velocity (ω)||Radius (r)|
|Car tire||20 m/s||100 rad/s||0.5 m|
|Merry-go-round horse||1.884 m/s||0.628 rad/s||3 m|
|Bicycle tire||22.62 m/s||75.4 rad/s||0.3 m|
|Electric fan blade||5 m/s||50 rad/s||0.2 m|
|CD spinning in a CD player||1.5 m/s||20 rad/s||0.06 m|
|Earth rotating on its axis||465 m/s||0.007 rad/s||6,371 km|
What’s the Difference Between Angular and Linear Speed?
The following table helps you understand the difference better, such as:
|Aspect||Angular Speed||Linear Speed|
|Definition||Rate at which an object rotates||Rate at which an object moves in a Straight line|
|Unit||Measured in radians per second (rad/s)||Measured in meters per second (m/s)|
|Symbol||Represented by ω (omega)||Represented by v|
|Formula||ω = θ/t||v = ωr|
|Example||Spinning wheel of a car||Speed of the car along a straight road|
Is Linear Speed Always Constant?
No, linear speed can vary. An object can experience acceleration or deceleration, leading to changes in its linear speed.
How is Linear Speed Relevant in Sports?
In sports, linear speed is crucial for determining the velocity of players or objects in motion, like a ball being kicked or thrown.
