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.
What else can I help you with?
What is Speed at a particular instant in time is?
That is called the instantaneous speed.
The rate of change in position at a given point in time?
Ah, honey, you're talking about velocity! Velocity is the rate of change in position at a specific point in time. It's like speed dating for math - how fast an object is moving at any given moment. So next time someone asks about the rate of change in position, you can confidently say, "Oh, that's just velocity, darling."
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.
What is the difference between instantaneous velocity and instantaneous speed?
Instantaneous velocity is a vector quantity that includes both the speed and direction of an object at a specific moment. Instantaneous speed, on the other hand, is a scalar quantity representing only the magnitude of the velocity without regard to direction.
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, if the instantaneous velocity of an object remains constant, then its instantaneous speed cannot change. Velocity is a vector quantity that includes both speed and direction. If the velocity is constant, it means both the speed and direction are constant.
At a given moment in time instantaneous speed can be thought of as the magnitude of instantaneous what?
Instantaneous speed can be thought of as the magnitude of instantaneous velocity. Velocity is a vector quantity that includes both speed and direction, while speed is a scalar quantity that only indicates how fast an object is moving.
How is velocity same from instantaneous speed?
Velocity is a vector quantity that includes both speed and direction, while instantaneous speed is the magnitude of velocity at a specific moment in time without considering direction. In other words, velocity accounts for the object's motion in a specific direction, whereas instantaneous speed is the rate at which an object is moving at a given instant, regardless of direction.
Is a car's speedometer show instantaneous speed average speed or velocity?
A car's speedometer typically shows the instantaneous speed, which represents the current speed of the vehicle at any given moment. It does not show average speed or velocity.
At a given moment in time instantaneous speed can be though of as the magnitude of instantaneous of what?
At a given moment in time, instantaneous speed can be thought of as the magnitude of the instantaneous velocity of an object. Instantaneous velocity is the rate of change of an object's position at that specific moment in time.
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!)
What is the difference between Instantaneous speed and instantaneous velocity?
Speed has only size. Velocity has size and direction.If three drivers are driving their cars at 50 mph headed north, 50 mph headed south, and50 mph headed east, their speeds are all equal, but their velocites are all different.Instantaneous speed is the speed at an instant in time. A point on the edge of an LP record hasthe same instantaneous speed whenever you look at it.Instantaneous velocity is the velocity ... speed and direction ... at an instant in time. A point on theedge of an LP record has a different instantaneous velocity every time you look at it. Even thoughthe speed is always the same, the direction keeps changing.
When is speed equal to the magnitude of velocity?
Speed is equal to the magnitude of velocity when the object is moving in a straight line without changing direction. In other words, if the velocity vector is pointing in the same direction as the motion of the object, then the speed will be equal to the magnitude of the velocity.
