Velocity has magnitude and direction. Speed just has a magnitude. So without having a direction, the answer to your question is no.
Speed or velocity.
30 miles per hour north
We're not completely sure what you mean by "per hour per second". Going just by what we see in the question, it's an acceleration, not a velocity. "Six miles per hour north" would be a velocity.
A speed measurement indicating the distance traveled in an hour.
An example of velocity, which is a vector quantity that includes both speed and direction. The speed component is 80 miles per hour, while the direction component is northeast.
This measure is an example of velocity, which includes both a speed and a direction.
Velocity tells the speed AND what direction it's in. -- "30 miles per hour" is a speed. -- "30 miles per hour north" is a velocity. -- "30 miles per hour east" and "30 miles per hour south" are the same speed but different velocities.
A velocity vector includes both speed and direction.
'Velocity' should be compared with 'speed', and it should be understood that they're different. "30 miles per hour" is a speed. "30 miles per hour toward the south" is a velocity.
One example of Velocity is that if you are running in the same direction, your speed and velocity is the same. But if you are running AROUND the track, your speed is the same but your velocity is changing.
miles per hour: 9/112 (approximately 0.08) approximately 424 feet per hour approximately 129 meters per hour
An example of velocity is a car traveling at 60 miles per hour in a specific direction. Velocity is a vector quantity that includes both the speed of the object and its direction of motion.
