# How is constant speed and instantaneous speed alike?

Both are velocity functions. Instantaneous velocity is the derivative of the average velocity

They are both speed functions. Velocity is a vector related to speed but quite irrelevant in this context. An object rotating at a constant [angular] speed has a velocity that is continuously changing but that has no relevance.

No. Speed can remain constant when velocity changes, but velocity can't remain constant when speed changes.

Only if speed is constant. There can be no acceleration if the average speed is equal to the instantaneous speed.

Average and instantaneous speed are the same when the speed is constant during the time period you're interested in.

Average speed and instantaneous speed are both measurements of the speed of an object. The instantaneous speed measures how fast the object is going at a particular moment, while average speed shows how fast the object was moving in total over time.

Constant speed is constant velocity which means your going a certain speed in a straight line. Speed is just your speed at an exact moment also called instantaneous speed

Yes. Velocity is speed and direction so it can change velocity by changing direction.

Average speed allows you to change the instantaneous speed throughout the travel time, while during constant speed, one keeps there instantaneous speed at the same numberAverage speed is when a car is moving with a speed of 25 miles per hour. Constant speed is speed maintained consistency over time.

Answer #1:Constant speed is a speed that is maintained and stays the same.Instantaneous speed is a speed that goes up momentarily and thencomes back down.==================================Answer #2:A constant speed is one that has the same value now as it has hadat every previous time of interest, and the same as it will be for everyfuture time of interest.An instantaneous speed is one that conveys no information about anyprevious or future speed, only about the speed 'right now'.I just made this up on the fly. I think it's pretty good.

Suppose you accelerate in your car from stopped to 50 km.hr-1. When you were stopped your instantaneous speed was zero. At the end of the period of acceleration your instantaneous speed was 50 km.hr-1. If your rate of acceleration was constant then your average speed was 25 km.hr-1.

The types of speed are Constant Speed, Average Speed, and Instantaneous speed.GA GIRL ALL DAY 912 Thanks For Nothing

No instantaneous speed is not final speed.

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.

Instantaneous speed is, essentially, instant speed. An example sentence would be: The Camaro's instantaneous speed surprised most of the watchers.

Instantaneous speed is speed measured at a specific time. Speed is an average.

Everything has a value assigned to it called instantaneous speed, it is just impossible to measure instantaneous speed, which is why average speed is used. Instantaneous speed can be calculated or inferred, but not measured using any classical methods.

Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.

Yes. In smooth linear motion, the average speed and the instantaneous speed are equal.

Instantaneous speed is what you see on your speedometer. Average speed is: how far you drove - divided by - how long it took.

You can calculate the instantaneous speed of an object through calculus using derivatives. You can more easily find the instantaneous speed of an object if there is constant acceleration by multiplying the rate of acceleration by time, then adding the initial velocity when time was equal to zero.

Instantaneous speed is the actual speed at the present time, and average speed is the total distance divided by the total time.

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.
