Tangential speed is how fast a point on a circular object is moving at a certain distance from the center whereas rotational speed is how many degrees (or radians) a point on the circle goes through in a period of time.
Every point on a circle has the same rotational speed. The further out you go from the center, the higher the tangential speed is.

How many linear meters in 2 squire meter?
A linear metre was a unit of length. A square metre is a unit of area. The two units are therefore incompatible.
How much us 2000 square meters in linear feet?
A square metre is a unit of area. A linear foot is a unit of length. The two units are therefore incompatible.
What is A sentence using tangential?
Look, the tangential line is touching a semi circle.
What are two units of measure for speed?
In order to measure speed, a unit for distance and a unit for time must be used. Common units with which speed is expressed are meters per second (m/s), miles per hour (mph), and kilometers per hour (km/h).
How many metric inches is 5.0 cu feet?
NO Such unit as 'Metric Inches'. In the metric system of linear measure, the unit is 'centimetres / metres'. In the Imperial System of linear measure, the unit is inches / feet. Next you are referring to linear measure, then at the end refer to volume measure; 'Cubic feet', Please clarify your question.
What is linear speed called when something moves in a circle?
Tangential speed
What is the SI unit for tangential speed?
meters per second
At a given rotational speed how does linear speed change its distance from the axis changes?
In The Center Of The Rotating Platform Right At Its Axis You Have No Linear Speed At All, But You Do Have Rotational Speed. Your Rotational Speed would Stay The Same But As You Move Away From The Center Your Linear Speed Gets Faster And Faster. If You Move Twice As Much From The Center Your Linear (Tangential) Speed Would Also Be Twice as Much
What is tangential speed?
Linear speed is the distance traveled per unit of time, while tangential speed (or tangential velocity) is the linear speed of something moving along a circular path.[5] A point on the outside edge of a merry-go-round or turntable travels a greater distance in one complete rotation than a point nearer the center. Traveling a greater distance in the same time means a greater speed, and so linear speed is greater on the outer edge of a rotating object than it is closer to the axis. This speed along a circular path is known as tangential speed because the direction of motion is tangentto the circumference of the circle. For circular motion, the terms linear speed and tangential speed are used interchangeably, and both use units of m/s, km/h, and others.Rotational speed (or angular speed) involves the number of revolutions per unit of time. All parts of a rigid merry-go-round or turntable turn about the axis of rotation in the same amount of time. Thus, all parts share the same rate of rotation, or the same number of rotations or revolutions per unit of time. It is common to express rotational rates in revolutions per minute (RPM) or in terms of the number of "radians" turned in a unit of time. There are little more than 6 radians in a full rotation (2π radians exactly). When a direction is assigned to rotational speed, it is known as rotational velocity or angular velocity. Rotational velocity is a vector whose magnitude is the rotational speed.Tangential speed and rotational speed are related: the greater the RPM's, the larger the speed in meters per second. Tangential speed is directly proportional to rotational speed at any fixed distance from the axis of rotation.[6] However, tangential speed, unlike rotational speed, depends on radial distance (the distance from the axis). For a platform rotating with a fixed rotational speed, the tangential speed in the center is zero. Towards the edge of the platform the tangential speed increases proportional to the distance from the axis.[7] In equation form:where v is tangential speed and ω (Greek letter omega) is rotational speed. One moves faster if the rate of rotation increases (a larger value for ω), and one also moves faster if movement farther from the axis occurs (a larger value for r). Move twice as far from the rotational axis at the center and you move twice as fast. Move out three times as far and you have three times as much tangential speed. In any kind of rotating system, tangential speed depends on how far you are from the axis of rotation.When proper units are used for tangential speed v, rotational speed ω, and radial distance r, the direct proportion of v to both r and ω becomes the exact equationThus, tangential speed will be directly proportional to rwhen all parts of a system simultaneously have the same ω, as for a wheel, disk, or rigid wand. (The direct proportionality of vto r is not valid for planets, because planets have different rotational speeds).
What is Dimension of speed?
The dimensions of speed are distance/time. Any unit of linear distance and any unit of time may be used.
Relationship between tangential speed and distance from the center of r?
tangential speed is directly proportional to rotational speed at nay fixed distance from the axis of rotation
What happens to tangential speed as rotational speed increases?
we can say that tangential speed of the object is linearly proportional to the distance from the center. Increase in the distance results in the increase in the amount of speed. As we move to the center speed decreases, and at the center speed becomes zero.
What is the tangential speed of the sun?
Speed, compared to what? The Sun's apparent speed in the sky, from our point of view, is approximately 15 degrees an hour. The Sun's speed around the center of the Milky Way is approximately 220 km/second. I believe that most of that is tangential speed.
Why you often consider the non-tangential limits and not tangential limits in the unit ball?

What is the unit of linear momentum?
(Any unit of mass) times (any unit of speed) is a unit of linear momentum. Angular momentum would need radians.In the SI (metric) system, it's kilogram meter per second kg.m.s-1 or Newton-second.
What is the relationship between linear speed and rotational speed?
(linear speed) = (rotational speed) x (radius or distance from the center) To use consistent measures, use radians/second for rotational speed, meters for the radius, and meters/second for the linear speed. If you know rotational speed in some other unit - for example, rpm (rotations per minute) - convert to radians per second first.
