Velocity is a quantity, and has a number associate with it. Note, however that it also has units associated with it, and a direction vector as well. Velocity, like speed, has magnitude associated with it. That will be units of distance (displacement) per unit of time. And velocity also incorporates the idea of direction, and will have to have that specified as well. A car may be going down the freeway, and it may be going 60 miles per hour. That's its speed. And if a we say a car is going 60, we understand that it's 60 mph. (In Britain, it might be 100, which is 100 kilometers per hour -- the understood units being the km/hr.) Only in that way can we say speed is a number. Same with velocity. The car's velocity might be 60 miles per hour east. And we can't leave off the direction vector.

What is the numerical ratio of velocity to speed an object?
The size of velocity and the size of speed are the same number. But velocity also has a direction and speed doesn't.
What is the difference between speed and velocity speed?
Speed is just a number; velocity includes information about the direction. In physical terms, speed is a scalar, whereas velocity is a vector.
The velocity time graph of a ball moving on surface of floor is shown in figure calculate the force acting on ball if mass of floor is 20gram?
a ball rolled across a horizontal table moved at cont ant velocity why?
What is the difference between force and power?
Force is the rate of change of momentum (which is the product of mass and velocity) whereas power is the rate of work done (product of force and displacement) In fact, it can be shown that power = force x velocity
What is the difference between between speed and velocity?
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 in avogadro's number?
Avogadro's number does not have anything to do with velocity.
How can we use integers to represent the velocity of a number?
You cannot because a number has no velocity.
What are all of the common factors of the number shown?
There is no number shown.
Is oxidation number shown with a subscript?
No: An oxidation number, if shown at all in a chemical formula, is shown with a superscript. The oxidation number is usually shown only for monatomic ions.
How would a measurement of velocity be shown?
like 9.8m/s and little 2 above the S
Do avogadro's number deal with velocity?
No.
How many levels of velocity can a car go?
Velocity (or speed) is a continuous quantity. There is no limit to the number of different values it can have ... that number is 'infinite'.Whatever two numbers you give me for velocity, no matter how close together they are, I can always find a number that is between them.
Why reynold's number is used to determine flow instead of velocity?
The two, Reynold's number and velocity, really measure quite different things.
What is the numerical ratio of velocity of speed of an object?
The size of velocity and the size of speed are the same number. But velocity also has a direction and speed doesn't.
What is the numerical ratio of velocity to speed an object?
The size of velocity and the size of speed are the same number. But velocity also has a direction and speed doesn't.
What is shown in each element?
An atomic number is shown in each element.
Does average velocity and average speed have the same number?
velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same.
