Angular velocity is a vector with a direction and angular speed is a scalar with no direction.
Velocity is speed with direction
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).
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.
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.
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.
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!)
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.
Velocity has a direction while speed doesn't. This is why we say that velocity is a vector quantity and speed a scalar quantity.
These are used in lots of engineering problems related to rotation.
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 number; velocity includes information about the direction. In physical terms, speed is a scalar, whereas velocity is a vector.
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.
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.
Velocity includes direction. And it's the 'difference', not the 'distance'.
Velocity also includes direction.
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.
Not really, they are basically the same
Speed is the rate of change in distance, whereas velocity is speed and direction of travel. Acceleration is the change in velocity (including direction).
