Question

What is the difference between instantaneous speed and average speed?

Answer 1

Instantaneous speed is average speed, but at very tiniy bit amount of time.
We call that
\[v=\frac{\Delta x}{\Delta t}\] when \(\Delta t\) approaches zero.

Answer 2

the speed at some instant of time is Instantaneous speed
the average speed in some duration of time is Average speed

Answer 3

Instantaneous speed is the speed in that instant.
Average speed is the average speed of an object over a period of time.

Answer 4

Thank You!!

Answer 5

You're welcome. I just studied it in my 9th grade physics so it is easy to remember.
