In summary, to find the instantaneous velocity at 1 s, you need to know something about the object's motion at that point. This can be determined by taking the derivative of the position function or estimating the slope of the tangent line on a position vs. time graph. Simply knowing the position at 1 s is not enough information.

by differentiating, or by drawing a tangent to the graph …

but what's the *rest* of this function?

This is the same as saying that velocity is the slope of the position vs. time graph.

Therefore, instantaneous velocity at 1s is the slope of the position vs. time graph at t=1s.

You need to know something about it

Now, what information are you
