Question

fill in the blank question to find the average speed of an object, we find the change in the distance divided by the time over which that change occurs. for the instantaneous speed, we must make the time interval very \boxed{} so that the speed does not change appreciably.

Explanation:

Instantaneous speed measures an object's speed at a specific moment. To approximate this, the time interval must be shortened enough that the object's speed does not have a noticeable change within that interval.

Answer:

short
