What is the relation between instantaneous speed and instantaneous velocity?

If I drive away from my house at 8:00 in the morning and return at 6:00 PM that same
evening with 50 more miles showing on the car, you know immediately that my average
speed for the day was 5 mph.
But you don't know a thing about how much of that time I was stopped, how much
in motion, or what my speed was at any moment between 8 and 6, because there's
no necessary relationship between instantaneous and average speed.
I guess it's probably true to say that there has to be some instant during any period
of time when the instantaneous speed must be equal to the average speed during
the same period. That sounds like a nice theorem, and its proof ought to be good
for some mathematical recreation, but it doesn't seem too useful.

∙ 14y agoInstantaneous speed: The speed at which I'm moving right now, this instant.
Average speed: (The distance I covered during some period of time) divided by (the length of time).
I may have had different instantaneous speeds at different points during that time.
Acceleration: The rate at which speed changes. Acceleration can also be instantaneous or average over
a period of time.

∙ 15y agoThey are the same thing, however velocity is 'in a given direction', speed is in any direction.

is constant during the time period you're interested in.

The rate of change in position at a given point in time?
The rate of change in position at a given point in time is instantaneous speed, instantaneous velocity.
What is Speed at a particular instant in time is?
That is called the instantaneous speed.
An objects speed at a particular moment in time is called?
Instantaneous Speed.
What is an example of the difference between speed and velocity?
Speed is what it is: speed. Velocity is speed in a given direction, a vector quantity.
What is the speed at any instant time known as?
Instantaneous speed is speed at any instant in time.
When is speed equal to the magnitude of velocity?
That is the case when you are talking about instantaneous speed and velocity - or when the velocity is constant. In the case of an average speed and velocity, this relation does not hold.
What is the difference between instantaneous velocity and instantaneous speed?
Speed, instantaneous or not, is a term used for how fast an object travels. Velocity, instantaneous or not, is a term used for how fast an object travels in a particular direction.
How is velocity same from instantaneous speed?
Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.
What is instantaneous velocity or speed?
It is the speed or velocity at a particular instant.
Does light speed accelerate or is it instantaneous velocity?
Instantaneous.
If the instantaneous velocity of an object remains constand can its instantaneous speed change?
No. Speed can remain constant when velocity changes, but velocity can't remain constant when speed changes.
Is a car's speedometer show instantaneous speed average speed or velocity?
It shows instantaneous speed.
What is the relation between velocity and acceretion?
That they have "Speed" in common.
The rate of change in position at a given point in time?
The rate of change in position at a given point in time is instantaneous speed, instantaneous velocity.
At a given moment in time instantaneous speed can be thought of as the magnitude of instantaneous what?
velocity
At a given moment in time instantaneous speed can be thought of as the magnitude of instantaneous .?
velocity
What the different between velocity and speed?
Speed is scalar quantity and velocity is a vector - velocity has both speed AND direction (You might say that velocity is speed with an attitude!)
