yes, velocity is speed with direction; average speed has no direction, bit average velocity does
The term "velocity", as used in physics, DOES have an associated direction. Most derived terms, such as "average velocity", also do.

Yes - just like any velocity, average velocity is a vector and has a direction associated with it. Speed, on the other hand is only an intensive property which has no specific direction associated with it. You could consider speed to be the magnitude of the velocity vector.
Velocity is speed and its direction. Average velocity is average speed and its direction.
There are several definitions. not just one. Average velocity in a direction = Average displacement (distance) in that direction/time Instantaneous velocity in a direction = derivative of displacement in that direction with respect to time Average velocity in a direction = Initial velocity in that direction + Average acceleration in that direction * time Instantaneous velocity in a direction = Definite integral of acceleration in that direction with respect to time, with initial velocity at t = 0 Then there are others in which time is eliminated.
Direction. Velocity has speed and direction
Speed does not have the direction associated with it, like velocity does.
Velocity has a direction component.Speed: 3 ft/sVelocity: 3 ft/s NNWSpeed does not have the direction associated with it, like velocity does.
by itself it is speed; if associated with a direction it is velocity
The average velocity in a particular direction = distance travelled in that direction / time taken. Velocity is a vector so the direction is important. If I go from A to B and then return to A my average velocity will be zero. My speed, on the other hand, will not be zero.
In order to find an average velocity, you need an average speed and an average direction. Average speed = (distance traveled) divided by (time to travel that distance) Average direction could be defined as the direction from the starting point to the end point.
The units are the same (metres per second) except that the velocity also has the direction of motion associated with it.
Speed is the rate at which something moves, and can be calculated by the equation: speed = distance / time. Speed does not have a direction associated with it. So if you are in a car and travel 60 miles in 2 hours, your average speed would be 30 miles per hour. Velocity is very similar to speed, but it does have a direction associated with it. That is the only difference.
Average velocity equals the average speed if (and only if) the motion is in the same direction. If not, the average speed, being the average of the absolute value of the velocity, will be larger.
Average velocity in a direction is calculated as the displacement in that direction divided by the total time taken. As the time interval is reduced, the displacement over that period also reduces and the limiting value of that ratio is the instantaneous velocity.
It means that an object with a negative average velocity is moving in the opposite direction (of course according to the chosen positive direction of the predefined frame).
Velocity is acceleration and direction put together. The velocity of something changes if either acceleration or direction changes. Speed is just the average MPH measure. Velocity is not acceleration and direction put together. In that kind of description, velocity is is speed and direction put together. Velocity is a vector, whose size is the speed.
Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.
No, it is not. At a constant speed, yes. But velocity has a direction component, and by running on (following) a curve, a change of direction (and, therefore, velocity) will have to be made. Again, note that speed can stay the same, but velocity has a direction vector associated with it that cannot be ignored.
The average velocity has two parts to it: The average speed and the average direction. The average speed is: (the distance you travel between 0 and 3 seconds) divided by (3). The average direction is: the direction from (the place where you started at 0 seconds) to (the place where you finished at 3 seconds).
If, as you say, its acceleration is "constant", then the average is exactly equal to that constant.
The velocity of an object, in a given direction, is the displacement in that direction divided by the time period for the displacement.
As long as there is no change in direction then they are effectively the same.
If the car has an average speed of 65 mph, when it returns to its starting point, it will have a displacement of zero and an average velocity of zero, because velocity has both speed and direction.
No. Velocity implies both a magnitude and a direction.No. Velocity implies both a magnitude and a direction.No. Velocity implies both a magnitude and a direction.No. Velocity implies both a magnitude and a direction.
It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.
Yes, if the car moves in only one direction.
