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 else can I help you with?
Use the following graph of a car traveling on a straight northerly path to answer this question. At what time would the magnitude of the velocity reach 72 kmhr?
The magnitude of the velocity would reach 72 km/hr at around 5 seconds based on the graph shown. This is when the slope of the velocity-time graph is steepest, indicating the highest rate of change in velocity.
How do you find the average velocity pressure?
To find the average velocity pressure, you would need to calculate the total velocity pressure and divide it by the number of measurements taken. This would give you the average velocity pressure over the measurement period.
What is the numerical ratio of velocity to speed an object?
The ratio of velocity to speed of an object is always equal to 1 since velocity and speed are both scalar quantities that denote the rate of an object's motion, with velocity also specifying the direction of motion.
Is it true that for velocity you must have a number a unit and a direction?
Yes, velocity is a vector quantity that includes magnitude (number), unit (e.g. m/s), and direction (e.g. north). The direction of the velocity vector indicates the motion of the object (e.g. moving east at 5 m/s).
Is deceleration a form acceleration?
Acceleration and deceleration are both the rate at which velocity changes, Deceleration is a negative acceleration. In an equation the rate of deceleration is shown as a negative acceleration valueCentripetal acceleration is different and represents the rate of change of tangential velocity. There is no equivalent centripetal deceleration.
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.
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.
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 is absolute number shown?
|2|
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.
Would you use a positive or negative number to represent the velocity of a descending hot-air balloon?
I don't think velocity can be a negative number... Use positive.
