Rate Of Speed Have you ever heard of people using the phrase "rate of speed" before? Well, mainly on TV during one of our local news. Usually it is during a description of some vehicular traffic incident, and some vehicle was described as moving at a "high rate of speed". What they really want to say is simply that the vehicle was moving very fast, but somehow, they think saying "high rate of speed" sounds "sexier". This, of course, is rather inaccurate. Typically, when say say "rate of something", we usually mean the time rate of change. In calculus, it is d/dt of something, i.e. the time derivative. So when one say "rate of speed", one is actually saying ds/dt, where "s" is speed. This is ACCELERATION! So, if you write for some news broadcast, and you want to say that a vehicle moves very fast, just say "high speed" and NOT "high rate of speed". If your producer or proof reader disagree, ask him/her to open a physics textbook. Thanks to ZapperZ.

What is the rate of motion at any given moment?
The instantaneous speed is the rate of motion at any given time.
Speed of an object at any given time?
It is the distance covered in a unit of time.
Why is the speed limit on a highway a unit rate?
Any type of measurement is a unit rate. The speed limit is a measurement of time and distance.
What is called speed of an object at a given instant?
An objects speed at any particular moment in time is known as its instantaneous velocity. This is the rate of change or the derivative of the objects position.
How do speed and position relate to one another?
If one knows the POSITION and SPEED of an object at a given time, one can then predict the position of that object relative to the original POSITION at any time afterwards. Also useful to know would be the DIRECTION in which it was moving - which would enable a more accurate prediction of it's subsequent position; and any rate of ACCELERATION (or its negative, deceleration), i.e. the rate of change of speed, as this would also affect the object's subsequent position.
What is the rate of motion at any given moment?
The instantaneous speed is the rate of motion at any given time.
Speed of an object at any given time?
It is the distance covered in a unit of time.
Speed that is the same at any given time is?
Speed that is the same at any given time is uniform speed.
What is the rate ofotion at any given instant?
rate of motion is speed or velocity
What is the defintion for instantaneous speed?
the rate at which an object is moving at any given moment in time. from the physical science glossary
When are speed and average speed the same?
Average speed is an average value of speed over a given time. If your speed is constant (not changing), then your average speed will equal your speed at any given moment in time.
What Is the speed of an object at any instant of time.?
Instantaneous speed-the speed of an object at any instant time. When you ride in a car, the instantaneous speed is given by the speedometer.
Why is the speed limit on a highway a unit rate?
Any type of measurement is a unit rate. The speed limit is a measurement of time and distance.
What is called speed of an object at a given instant?
An objects speed at any particular moment in time is known as its instantaneous velocity. This is the rate of change or the derivative of the objects position.
What is stantaneous speed?
Stantaneous speed is how fast an object moves at any given time.
What is the difference between actual speed and average speed?
Actual speed is the speed you are traveling at any given moment at any given point. Average speed is figured by dividing the distance you traveled by the time it took you to drive that distance.
How do speed and position relate to one another?
