What is Difference between angular velocity and angular speed?
Angular velocity is a vector with a direction and angular speed is a scalar with no direction.
linear velocity is a change of speed in a linear fashion. Angular speed is the rate of change of angle with respect to time. These two are convertible in a case of a circle motion. the lenght of an arc is l = RO. where O is the angle. hence v= l/t and therefore v=RA where A = O/t.
Angular velocity is given as radians per second; angular speed is also the same thing. Velocity is a vector with magnitude and direction and speed a scalar with magnitude only. The magnitude is identical; velocity will define the direction of rotation ( clockwise or counterclockwise).
Velocity is speed with direction
The technical difference is that speed has no direction but velocity has one.
velocity is speed with direction; velocity is a vector and speed is a scalar
The difference between an object's speed and an object's velocity is that the object's speed is how fast it is going, and the object's velocity is how many units of speed the object has traveled.
"Direction". The only difference between velocity and speed is that velocity is a vector while speed is a magnitude. Therefore, velocity has a direction, while speed does not.
The main difference between speed and velocity involves direction. Velocity involves an object moving in a particular direction.
Linear speed is the speed of an object along its path of motion. Angular speed is how fast an object is changing its angle (rotating) about an axis.
Direction. Velocity has speed and direction
Speed is what it is: speed. Velocity is speed in a given direction, a vector quantity.
The main difference between speed and velocity involves direction.
Speed is scalar quantity and velocity is a vector - velocity has both speed AND direction (You might say that velocity is speed with an attitude!)
http://wiki.answers.com/Q/The_difference_of_speed_and_velocity" The difference between speed and velocity is that speed is a scalar quantity(that have only magnitude) and velocity is a vector quantity(that have both magnitude and direction).
Speed is just a magnitude (or number); velocity includes information about the direction as well. In physical terms, speed is a scalar, whereas velocity is a vector.
Velocity has a direction while speed doesn't. This is why we say that velocity is a vector quantity and speed a scalar quantity.

Speed is just a number; velocity includes information about the direction. In physical terms, speed is a scalar, whereas velocity is a vector.
What are the practical applications of Angular Speed Angular Displacement Angular Velocity and Angular Momentum?
These are used in lots of engineering problems related to rotation.
Speed is a scalar and velocity is a vector (has a direction). Speed can be said to be omni-directional like the speed of light.
Angular velocity means how fast something rotates. The exact definition of angular momentum is a bit more complicated, but it is the rotational equivalent of linear momentum. It is the product of moment of inertia and angular speed.
The direction of angular acceleration comes from whether the angular speed of the object is clockwise or counterclockwise and whether it is speeding up or slowing down. The direction of the angular acceleration will be positive if the angular velocity is counterclockwise and the object's rotation is speeding up or if the angular velocity is clockwise and the object's rotation is slowing down The direction of the angular acceleration will be negative if the angular… Read More
Speed is the rate of change in distance, whereas velocity is speed and direction of travel. Acceleration is the change in velocity (including direction).
Velocity includes direction. And it's the 'difference', not the 'distance'.
Velocity also includes direction.
Speed is exactly like velocity, except velocity has a fixed direction. So speed would be 50mph, whereas velocity would be 50mph NE
the instantaneous velocity or speed is the speed a body travels at a particular and average velocity is the total distance an object
Speed is how fast you are going. Velocity is how fast you are going and what direction you are headed in.
Speed is a scalar (Only has magnitude, no direction) Velocity is a vector (Has magnitude and direction)
That is analogous to linear speed and velocity, but for rotation. Whereas a linear speed (or velocity) is expressed in meters per second (or some other units of distance / time), the angular speed or velocity is expressed in radians / second (or some other units of angle / time). Of course, when something rotates, there is also a linear speed, but different parts of an object rotate at different linear speeds, whereas the angular… Read More
Speed only tells how fast something is going, while velocity tells speed and direction.
Speed is a scalar quantity with out direction, velocity is a vector quantity with a direction, The magnitude of a velocity, |V| is its speed. So all velocities have a speed, including a speed of zero.
velocity is rapid speed and Location is a place or a certain spot
speed is how fast an object is moving, velocity is how fast an object is moving in a given direction.
Avg velocity is the speed you are going. Constant acceleration is the rate you increase your speed. = =
Not really, they are basically the same
Velocity is speed with direction. To show the difference, show the direction of an object compared with speed alone. For example, a speedometer shows speed alone, a car on a road can show speed and direction.
Both are velocity functions. Instantaneous velocity is the derivative of the average velocity * * * * * They are both speed functions. Velocity is a vector related to speed but quite irrelevant in this context. An object rotating at a constant [angular] speed has a velocity that is continuously changing but that has no relevance.
Speed is a scalar quantity, and just has a magnitude (i.e. you may travel in any direction), while velocity is a vector, and requires a direction (e.g. the difference between the speed 25km/h, and the velocity 25km/h North)
Ignoring the fact that some clocks "jump", for example once a second, each of the three arms moves at constant angular velocity. The speed, in this case, is constant; the velocity is not since the direction changes. On the other hand, sometimes people use a vector to describe an angular velocity. Angular momentums add nicely with vector representation.
speed =dist/time velocity=displacement/time difference is that velocity depicts the direction in which a body is moving as displacement is one of it"s attriebutes but speed does not
A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed.
When a direction is specified, it is called velocity. When the direction is not specified, it is called a speed. (That's the difference between a vector and a scalar.)
Speed refers to velocity, whereas agility refers to coordination.
speed is a scalar quantity ie it has no directions...........whereas velocity is a vector quantity ie it has directions...................Also speed has distance n velocity has displacement
A velocity is a speed, including a specification of a direction. In physics, this is called a vector.
Speed is how fast the movement is. It contains only a magnitude. Velocity is speed plus a direction, and is known as a vector. Speed: 40mph Velcoity:40mph/east
How many times centripetal force will increase if the angular speed of a body moving with uniform speed moving in a circle is increases?
Centripetal acceleration, and therefore centripetal force, is proportional to the square of the angular velocity. For example, if you increase the angular velocity by a factor of 10, the centripetal force will be increased by a factor of 100.
