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.
Direction. Velocity has speed and 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.
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.
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.
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.
